Abstract:
Photonic membranes are the most widely used kind of 2D photonic crystals in signal processing. Nevertheless, some important aspects of electromagnetic field behavior in membrane like photonic crystals (MPCs) need detail investigation. We develop the approach close to resonant coupling modes method which unites both external and intrinsic problems, in-plane and out-of-plane geometries, and resonator properties of MPC. The resonator standing modes are excited by an external source through the special inputs and may be controlled due to the nonlinear coating. Typical photonic manifestations are studied for Si/SiO2 2D membrane resonators of rectangular.

Abstract:
Introduction. The development of new amplifiers and generators of the Ku- and K-bands (12…27 GHz) for use in onboard equipment is increasingly attracting research interest. Low-voltage multi-beam klystrons (LMBK) can be a promising element base for such devices. Serious problems are associated with the need to suppress parasitic modes of oscillations in NMLK operating in the centimeter and millimeter range. A possible solution is to use double-gap photonic-crystal resonators (DPCR) in LMBK. Another promising direction for improving the characteristics of such resonators is to use resonant segments of strip lines with fractal elements. In this case, the strip lines are placed on a dielectric substrate in the interaction space. Such resonators exhibit new properties that are useful for klystrons (an increase in characteristic impedance, suppression of the spectrum of unwanted frequencies, a reduction in mass and dimensions).Aim. Determination of an optimal set of electrodynamic and electronic parameters of double-gap photonic-crystal resonance systems with fractal elements "Minkowski Island" when operated as part of the LMBK resonator system, excited on π- and 2π-modes of oscillation.Materials and methods. To calculate the electrodynamic parameters of resonators, the method of finite differences in the time domain was used. The well-known Wessel-Berg method was used to calculate electronic parameters, such as the Ge / G0 electronic conductivity and the coupling coefficient M.Results. The main electrodynamic parameters of the resonator – Q-factor, resonant frequency and characteristic impedance – were investigated. The electronic parameters of the resonator, the coefficient of coupling with the electron beam, and the relative electronic conductivity for π- and 2π-modes of oscillations were calculated. In this case, three variants of the resonator with zero, first and second iterations of the fractal element were investigated. The amplitude-frequency characteristics of the resonator were investigated with a change in the pitch of the photonic crystal lattice. An estimation of the inhomogeneity of the high-frequency field in the interaction spaces of the resonator was carried out. Operational conditions were determined simultaneously for two types of oscillations without self-excitation.Conclusion. The results can find application in the development of resonator systems for klystron-type devices in the centimeter and millimeter ranges.

Abstract:
Abstract A design for a high quality factor photonic crystal ring resonator (PCRR) is presented. The PCRR is based on pillar type photonic crystals, which consist of a hexagonal array of silicon rods. The cavity is created by removing elements from the regular photonic crystal (PhC) grid. Achieving strong confinement of light intensity in the low index region is the advantage of this PCRR. In that manner, the interaction of light and analyte, which can be a liquid or a gas, will be enhanced. The high quality factor of the cavity (Q=1.0229\times {10}^{5}), along with strong overlap between the field of the resonant mode and the analyte as well as the low group velocity of PCRR modes yield enhanced light-matter interaction. An enhancement factor of \gamma =2.127\times {10}^{4} compared to the bulk light absorption in a homogenous material provides the potential for highly sensitive gas detection with a photonic crystal ring resonator.

This paper analyzes the modality of two-dimensional photonic crystal micro-resonators by adopting equivalent refractive index mode. In this paper, it controls the optical field distribution only through altering the thickness of light guide layer, while the parameter like resonator structure and crystal lattice arrangement remain stable. It discusses that it would arrive at a satisfactory photon locality while the refractive index of light guide layer material is gallium nitride , the thickness of light guide layer is and its equivalent refractive index is 2.1.This reveals the influence of micro-resonator light guide layer’s thickness towards the modality, providing a preferable pre-estimate method for the actual research of micro-resonators with higher quality.

Abstract:
Chirped mirrors have underpinned advances in ultra-fast lasers based on bulk optics but have yet to be fully exploited in integrated photonics, where they could provide a means to engineer otherwise unattainable dispersion profiles for a range of nonlinear optical applications, including soliton frequency comb generation. The vast majority of integrated resonators for frequency combs make use of microring geometries, in which only waveguide width and height are varied to engineer dispersion. Here, we present an integrated photonic-crystal Fabry–Pérot resonator made of gallium phosphide (GaP), a material exhibiting a Kerr nonlinearity 200 times larger than that of silicon nitride and a high refractive index that permits the creation of strongly chirped photonic-crystal mirrors. Leveraging the additional degrees of freedom provided by integrated chirped mirrors, we disentangle optical losses from dispersion. We obtain an overall dispersion that is more anomalous than that achievable in both silicon nitride and gallium phosphide ring resonators with the same free-spectral range (FSR), while simultaneously obtaining higher quality factors than those of GaP ring resonators. With subharmonic pulsed pumping at an average power of 23.6 mW, we are able to access stable dissipative Kerr frequency combs in a device with a FSR of 55.9 GHz. We demonstrate soliton formation with a 3-dB bandwidth of 3.0 THz, corresponding to a pulse duration of 60 fs. This approach to cavity design based on photonic-crystal reflectors offers nearly arbitrary dispersion engineering over the optical transparency window of the nonlinear material.

Abstract:
AbstractPoint-of-care (POC) devices are essential for rapid testing of samples for early diagnosis of diseases. The accuracy and the sensitivity of the POC device depend mainly on the biosensors. The currently used POC devices require specialized operating personnel, long sample preparation time and high equipment costs. We aim to explain a bio-sensing concept using a photonic crystal (PC) resonator that would mitigate the drawbacks of the present sensing techniques. Photonic crystals consist of spatially arranged dielectric materials presenting a band gap that prevents electromagnetic waves of certain frequency range to propagate through it. PC resonators have shown to have very high sensitivities for bio-sensing applications at THz frequencies. A PC resonator with a high Q-factor is designed and simulated to detect the changes in the surrounding dielectric permittivity. As an application for detecting specific biomolecules, a protocol for surface functionalization has been explained. This will enable the selective binding of biomolecules from the sample. Shift in resonant frequency and attenuation in magnitude at the peak resonant frequency can be observed from the simulation results. These changes in the resonator properties can be indicative of the presence of a particular biomolecule or pathogen and its concentration within the sample.

Abstract:
We achieve the effective modulation of coupled-resonator-induced transparency (CRIT) in a photonic crystal system which consists of photonic crystal waveguide (PCW), defect cavities, and a multilayer graphene-insulator stack (MGIS). Simulation results show that the wavelength of transparency window can be effectively tuned through varying the chemical potential of graphene in MGIS. The peak value of the CRIT effect is closely related to the structural parameters of our proposed system. Tunable Multipeak CRIT is also realized in the four-resonator-coupled photonic crystal system by modulating the chemical potentials of MGISs in different cavity units. This system paves a novel way toward multichannel-selective filters, optical sensors, and nonlinear devices.

In the working frequency range, 0.212–0.238 THz, the isolation of the circulator was better than 20 dB, and the insertion loss was better than 1 dB.

Abstract Transmission efficiency, quality factor, crosstalk levels and number of output channels are the most crucial parameters in designing optical demultiplexers, suitable for wavelength division multiplexing applications. In this paper we proposed an 8-channel optical demultiplexer based on photonic crystal ring resonator. For performing wavelength selection task we used eight ring resonators. The resonance wavelength of the ring resonators depends on the dimensions of the ring core, therefore we choose eight different values for the lattice constant of the ring resonators core section. The average channel spacing of the structure is about 3 nm the transmission efficiency in most of the channels is equal or more than 99 % except in one channels whose transmission efficiency is 85 %.

Abstract:
The purpose of this paper is to examine the design, simulation, and optimization of a demultiplexer optical system using photonic crystal resonators. Utilizing the distinct properties of photonic crystals, the proposed device achieves high-quality resonances, efficient wavelength separation, and minimal crosstalk. These characteristics are crucial for enhancing the performance of dense wavelength division multiplexing (DWDM) systems, which require precise and efficient channel separation to manage increasing data traffic. Extensive simulations conducted with the RSoft CAD tool explore the impact of varying resonator parameters such as refractive index, geometric dimensions, and material composition on the device's performance. The results indicate substantial improvements in transmission efficiency and quality factor, with average values of 98.675% and 3131.125, respectively. Furthermore, the ability to fine-tune these parameters allows for the customization of the demultiplexer to specific wavelength ranges, making it highly adaptable for various telecommunications applications. This research aims to propel the development of compact, high-performance photonic devices that meet the growing demands of modern communication networks, ultimately contributing to more efficient and reliable optical communication systems.

Abstract:
This paper presents a novel fabrication method for three-dimensional (3D) ceramic point defect photonic crystals. The 3D defect photonic crystal, which possesses an air cavity, has been designed by cutting a rectangular shape (3.5 mm × 3.5 mm × 7 mm) in the centre of a photonic crystal with a diamond lattice structure model (50 mm × 30 mm × 20 mm) with a lattice constant of 7 mm. Stereolithography (SL) technology was applied to fabricate resin moulds with an inverse-diamond structure incorporating the defect, and high solid content aqueous ceramic slurry was prepared and injected into the moulds. After gel-casting, drying, and high-temperature sintering, ceramic 3D photonic crystals with intact structure and minimal shrinkage were obtained. The penetration of an electric field with resonant modes of about 3 mm into the host lattice was observed by measuring the <110> direction of the samples, which resulted from the rectangular air cavity resonator. The results show that this method can be used to fabricate ceramic 3D point defect photonic crystals with a complex 3D structure.

Abstract:
AbstractIn this article, a 2D photonic crystal (PC)-based optical filter has been designed using a PC ring resonator. The resonator used is of square type with a square lattice constant, which has been designed by increasing the radius of the inner rods of the resonator. The filter designed can separate the light of the wavelength of 1545.3 nm with a transmission coefficient of 98 %. The bandwidth of the above wavelength is equal to 0.5 nm and hence the quality factor of the device at this wavelength is equal to 3091. The effects of the structural parameters, such as the refractive index, the lattice constant, the radius of the dielectric rods, the radius of the inner rods of the resonator on the behavior of the proposed device, are fully investigated. To obtain the photonic band gap, the plane wave expansion method is used. In addition, the finite difference time domain method is used to examine, simulate, and to obtain the output spectrum of the structure. The designed structure has both high transmission coefficient and quality factor. Comparatively speaking, it is also simple to design which justifies its use in other photonic crystal-based optical devices.

High-aspect-ratio photonic crystal air-hole fabrication on bulk Lithium Niobate (LN) substrates is extremely difficult due to its inherent resistance to etching, resulting in conical structures and high insertion losses. Here, we propose a novel coupled resonator photonic crystal (CRPC) design, combining a coupled resonator approach with that of Bragg gratings. CRPC design parameters were optimized by analytical calculations and FDTD simulations. CRPC structures with optimized parameters were fabricated and electrooptically tested on bulk LN annealed proton exchange waveguides. Low insertion loss and large electrooptic effect were observed with the fabricated devices, making the CRPC design a promising structure for electrooptic device applications.

Abstract:
We propose a controllable topological add-drop filter based on magnetic–optical photonic crystals. This add-drop filter is composed of two straight waveguides and a hexagonal photonic crystal ring resonator. The waveguide and ring resonator are constructed by three different honeycomb magnetic–optical photonic crystals. The expanded lattice is applied with an external magnetic field so that it breaks time-reversal symmetry and the analogous quantum spin Hall effect simultaneously. While the standard one and the compressed one are not magnetized and trivial, the straight waveguide supports pseudospin-down (or pseudospin-up) one-way states when the expanded lattice is applied with an external magnetic field of +H (or −H). The ring resonator possesses multiple resonant modes which can be divided into travelling modes and standing modes. By using the travelling modes, we have demonstrated the function of the add-drop filter and realized the output port control by changing the direction of the magnetic field. Moreover, a large tunable power ratio from near 0 to 52.6 is achieved by adjusting the strength of the external magnetic field. The structure has strong robustness against defects due to the topological protection property. These results have potential in wavelength division multiplexing systems and integrated topological optical devices.

Abstract:
Wireless networks are considered a hot topic in dealing with data without need to routers or other infrastructures. Each node has a part of routing responsibility. This result to a huge of data in forwarding to other nodes and will need high speed to process. Photonic crystal applications come to solve the necessity for such speed with small circuitry area. One of the main factors that affect their operation is the structure topology. Ring resonator, cavity based structures, self-collimation, and waveguide approaches are some of these topologies. OR gate is proposed in this paper to be simulated and evaluated as one of the basic element block. This design is built on a square lattice- photonic crystal construction on a ring resonator basis. Rotation of 90, 180, and 270 degrees are applied in clockwise direction. Sensitivity analysis, and carefully rod locations are considered to obtain remarkable performance. Minimum size and highly data rate are two characteristics that discriminates this design. The minimum size of 51.48 μm2 is obtained. The bit rates of 1.35, 6.35, 3.2, and 2.53 Tbs are calculated with the 0, 90, 180, and 270 degrees, respectively. Comparison table is well organized for the recently published photonic crystal OR-gate that based on ring resonator. Finite difference time domain and Plan wave expansion method are used to analyze the proposed structure at 1.55μm wavelength to verify OR- gate operation.

Abstract:
In this paper, the concept of photonic crystals (PhCs) is fundamental to designing and simulating an all-optical logic gate device. We proposed an all-optical switch composed of two-dimensional (2D) photonic crystal waveguides with a central photonic crystal ring resonator (PCRR). The new all-optical NAND logic gate device comprises two linear waveguides coupled to each other through a single compact PCRR. The plane wave expansion (PWE) and finite-difference time-domain (FDTD) methods are applied to simulate the properties of the system. The structure is implemented on the operational wavelength of 1700 nm on an air wafer of only 12 μm × 12 μm. Indeed, the simulation results show that the proposed all-optical NAND gate is a strong candidate for ultrafast photonic integrated circuits (PICs) for applications in optical communications, being advantageous with high transmitting power, with simple design, and without the use of optical amplifiers and nonlinear materials.

Abstract:
The position-dependent extraordinary optical properties in near-zero-permittivity range for a one-dimensional superconducting photonic crystal consisting of alternating superconductor and dielectric layers are theoretically investigated by using the transfer matrix method. Based on the calculated reflectance spectrum, it is shown the extraordinary optical propriety depends on the relative position between the threshold wavelength and the photonic band gap. By suitably choosing the thickness of the superconducting or dielectric layer, one can design a transmission narrowband filter or resonator to satisfy their needs without introducing any physical defect in a superconducting photonic crystal.

Abstract:
We numerically demonstrated single-port coherent perfect loss (CPL) with a Fabry–Perot resonator in a photonic crystal (PC) nanobeam by using a perfect magnetic conductor (PMC)-like boundary. The CPL mode with even symmetry can be reduced to a single-port CPL when a PMC boundary is applied. The boundary which acts like a PMC boundary, here known as a PMC-like boundary, and can be realized by adjusting the phase shift of the reflection from the PC when the wavelength of the light is within the photonic bandgap wavelength range. We designed and optimized simple Fabry–Perot resonator and coupler in nanobeam to get the PMC-like boundary. To satisfy the loss condition in CPL, we controlled the coupling loss in the resonator by modifying the lattice constant of the PC used for coupling. By optimizing the coupling loss, we achieved zero reflection (CPL) in a single port with a PMC-like boundary.

In this paper, a millimeter-wave Y-shaped circulator based on magneto photonic crystals is demonstrated. The triangular lattice photonic crystal with Y-shaped line defect waveguide is constructed by Al2O3 ceramic posts.

The transmission characteristics of the circulator experimented under the external magnetic bias H0 = 300 Gs. In working frequency range 24∼28 GHz the isolation of circulator is better than 20 dB, and the best insertion loss is as low as 0.2 dB. The experimented results are well agreed with the simulation results.

Abstract This structure proposes the creation of the optical biosensor that can be used to detect vitiligo caused to pigment loss. For accomplishing this, a pair of 2-D photonic crystal structures, such as the K3 and K7 resonators, are examined. The study of both resonator structures is succeeded using (FDTD) Finite Difference Time Domain. The Lumerical simulation tool is used to model these structures in the Finite Difference Time Domain (FDTD). The subsequent optical properties of different pigmentation in human skin are investigated, and the refractive indexes information are entered into Lumerical (FDTD) to find variations in the refractive indexes of several pigments that produce vitiligo.

Abstract:
A high-performance photonic crystal (PhC) concentric dual-microring resonator (PhCCDMRR) for refractive index sensing is proposed in this paper. It confines the energy into PhC air holes to enhance the light–matter interaction, and the increased modal area of the concentric rings improves the sensing sensitivity. The slow-light effect near the photonic bandgap results in a PhC waveguide with a maximum group index of 18.2. In the transmission spectrum, a high extinction ratio of 22 dB is achieved. This sensor obtains a refractive index (RI) sensitivity of 265 nm/RIU (RI unit) using sodium chloride solution as samples, which has promising applications in RI sensing.

Abstract In this paper, we proposed optical filter based on two-dimensional photonic crystal elliptical channel for wavelength division multiplexing. We employed ring resonator with ellipse shaped core in proposed structure. The resonance wavelength of the ring resonators depends on two parameters: refractive index and radius of dielectric rods. We investigate the physical parameters governing the filter performance. Our results show that the transmission efficiency is 100 % due to nearly zero reflection and loss in channel. Band width of 4 nm and quality factor of 389 is obtained for filter. Also, the total footprint of proposed structure is 230.4 µm2 which makes it suitable for all optical integrated circuits.

Abstract:
In this manuscript, a chirped graded photonic crystal (PhC) resonator structure is optimized for biosensing applications. The proposed structure comprises a bilayer PhC with an aqueous defect layer, where the thickness grading within the material is introduced, considering alpha (α) as a grading parameter. The device performance is analytically evaluated using the finite element method (FEM). The impact of α, the resonator thickness, and the incidence angle on the device performance is analyzed. Further, the device’s ability to be used as a biosensor is evaluated, considering cholesterol as an analyte. The analytical results demonstrate an average sensitivity of 410 nm/RIU, a quality factor of 0.91 × 103, and a figure of merit (FOM) of 2.47 × 102RIU−1, showing 88.5% and 43% improvements in sensitivity and FOM compared to recently reported devices. The device’s superior sensing performance makes it suitable for medical and commercial applications, while the use of thickness grading addresses fabrication limitations, offering a robust framework for advanced photonic device design.

Abstract:
Abstract A two dimensional photonic crystal biosensor with high quality factor, transmission and sensitivity has been theoretically investigated using two dimensional finite difference time domain method (FDTD) and plane-wave expansion (PWE) approach. The studied biosensor consisted of two waveguide couplers and one microcavity formed by removing one air pore. Following analyte injection into the sensing holes and binding, the refractive index changes inducing a possible shift in the resonant wavelength. For the optimized structure, the biosensor quality factor is found to be over 49,767 and the obtained sensitivity is of order 15.2 nm/fg. Also, we investigated this structure in case of all air holes are applied as the functionalized holes with a sensitivity was found to be approximately equal to 292.46 nm∕RIU (refractive index units). According to the resonance cavity characteristics, the demultiplexing of different wavelengths can be achieved by regulating the radius of defects “r” inside the cavity. For this, A new design with 2D PCs for two-channel demultiplexer optofluidic biosensor has been proposed. The analysis shows that the response of each channel has a different resonant cavity wavelength and the filling of analyte in the selected holes cause resonant wavelength shifting, independently.
