Abstract:
The optical waveguides are produced in LiNbO3 substrate of three-component acceleration seismic geophone by lithography. Three-component acceleration seismic geophone detects changes in the external acceleration by detecting phase changes in the optical waveguides. The performance of optical waveguide directly affects the performance of three-component acceleration seismic geophone. Therefore, it is critical to measure and reduce the transmission loss of waveguides. The advantages and disadvantages of LiNbO3 crystal are introduced. The production process of Ti:LiNbO3 optical waveguide and its performance are presented. Some information about the types of transmission loss of optical waveguide and the measurement methods of optical waveguide loss are provided.

Abstract:
AbstractThis paper reports for the first time on a micromachined interposer platform for characterizing highly miniaturized multi-port sub-THz waveguide components. The reduced size of such devices does often not allow to connect them to conventional waveguide flanges. We demonstrate the micromachined interposer concept by characterizing a miniaturized, three-port, 220–330-GHz turnstile orthomode transducer. The interposer contains low-loss micromachined waveguides for routing the ports of the device under test to standard waveguide flanges and integrated micromachined matched loads for terminating the unused ports. In addition to the interposer, the measurement setup consists of a micromachined square-to-rectangular waveguide transition. These two devices enable the characterization of such a complex microwave component in four different configurations with a standard two-port measurement setup. In addition, the design of the interposer allows for independent characterization of its sub-components and, thus, for accurate de-embedding from the measured data, as demonstrated in this paper. The measurement setup can be custom-designed for each silicon micromachined device under test and co-fabricated in the same wafer due to the batch nature of this process. The solution presented here avoids the need of CNC-milled test-fixtures or waveguide pieces that deteriorate the performance of the device under test and reduce the measurement accuracy.

AbstractIn this article we give the solution of Maxwell's equations for the open circular cylindrical magnetoactive semiconductor plasma (-gyrotropy) waveguides. We describe the method that allowed us to arrive at a dispersion equation for the electrodynamical analyses of open circular cylindrical plasma (OCCP) waveguides. We numerically investigate the main and two higher modes' dispersion characteristics of p-Ge and p-Si waveguides placed in an external constant longitudinal magnetic field at several concentrations of two component hole charge carriers. We analyse the cutoff frequency and other electrodynamical characteristics of helicon modes with the left-handed (e+iϕ) circular polarization. We discover that the cutoff frequencies of the main mode and the working frequency range of OCCP p-Ge and p-Si waveguides are moving continuously towards the direction of higher frequencies when the hole concentration is increasing. We determine that the central frequency of the p-Si plasma waveguide is higher and its broadbandwidth is larger compared with the analogical p-Ge waveguide. We also numerically investigate the helicon mode cutoff frequencies of the infinitive p-Ge and p-Si plasma at several concentrations of two component hole charge carriers. We compare the cutoff frequencies of the helicon modes propagating in the infinite plasma and in the OCCP waveguides.

Abstract:
The tropospheric aerosol characterization is important for understanding environmental process as well as human health safety. In this study, the surface plasmon resonance sensor is proposed for the detection of ammonium sulfate which is an important component of aerosols. The reflectivity of proposed sensor waveguides is calculated as a function of the incident angle using the transfer matrix method. The performance of proposed sensors having sol-gel film of tetraethylorthosilane and thymolblue are studied and compared. Firstly, the dispersion characteristics are obtained for different modes, and it is observed that the modes are tightly bound in thymol blue waveguide in comparison to tetraethylorthosilane waveguide. Further, the magnetic field distributions are also studied and compared for proposed waveguide sensor configurations. It is found that the sol-gel film of thymol blue waveguide provides high sensitivity while tetraethylorthosilane waveguide shows high figure of merit.

Abstract:
An optical polymer waveguide is a key passive component for the optical interconnection. Design, fabrication, and characterization of high-performance waveguides have critical importance for the success of optoelectronic integration. In addition, defect effects, coupling, leakages, crosstalk, etc. are great concerns for the lightwave circuits. We present herein a fast, nondestructive, sensitive, real-time technique for detailed investigation of the propagation properties of planar optical waveguides and lightwave circuits. We use this technique to measure low-loss polymer waveguides on printed circuit board (PCB) substrates, and we have measured propagation losses of 0.065 dB/cm at 850 nm and 0.046 dB/cm at 980 nm. To the best of our knowledge, these are among the lowest losses reported to date for polymer waveguides on PCB substrates. A high-sensitivity CCD camera with a built-in integration function is utilized to observe the light streak in two dimensions through a two-lens imaging system. A few seconds to a few tens of seconds is needed for one complete measurement, compared with the sliding prism method, which requires several hours, and the cutback method, which requires even longer times. This technique can be used to evaluate not only the overall performance of a waveguide but also the local waveguide performance, as well as perform in-situ investigation of propagation properties (defect effect, bending effect, coupling, leakage, etc.). It can be extended to monitor the process of waveguide fabrication and alignment control during assembly for lightwave circuit integration.

Abstract:
Piezoelectric waveguide transducers possess great potential for the online monitoring of high temperature critical components, in order to improve their operational safety. Due to the use of a waveguide bar, the sensory device is not susceptible to high temperature environments, which enables the long-term service of the piezoelectric transducers. However, the coupling between the waveguide bar and the high-temperature component has been proven to be the most important part of the monitoring system. In order to effectively transmit waves through the junction of the waveguide bar and the monitoring target, it is necessary to research a reliable coupling method to connect the waveguide transducers with the host structure. In the present research, the feasibility of brazing coupling for wave propagation through the junction was investigated through experiments. Piezoelectric waveguide transducers were welded using various kinds of brazing filler metals. The experimental results indicate that the coupling effects of the brazing welding depend on the filler metals. At the same time, some filler metals for the effective coupling of the transducer and the target monitoring component were identified. The brazing coupling method was verified that it can non-dispersively and effectively propagate waves into the host structure with much better reliability than the conventional dry coupling approach. Moreover, the high-temperature experimental results show that the brazing-coupled waveguide bar system can work reliably and stably in high temperatures at 300 °C for a long time. This work strives to pave a solid foundation for the application of piezoelectric waveguide transducers for the structural health monitoring of high temperature critical components.

Abstract:
We investigate the edge effects of the optical analogue of the quantum relativistic Dirac solitons in binary waveguide arrays with Kerr nonlinearity when one tail of the Dirac soliton is truncated. We show that if the outermost waveguide of the binary waveguide array hosts the intense component of the truncated Dirac soliton, then Dirac soliton will be repeatedly bent towards the binary waveguide array edge. In the contrast, if the outermost waveguide of the binary waveguide array hosts the weak component of the truncated Dirac soliton, then Dirac soliton will be pushed away from the binary waveguide array edge. To the best of our knowledge, these unique features have not been found in any other systems.

Abstract:
In this work, all-optical plasmonic NOT logic gate was proposed by using metal-insulator-metal (MIM) plasmonic waveguides design. This logic gate is numerically analyzed by COMSOL Multiphysics 5.3a. Recently, plasmonics have attracted more attention due to its huge applications in all optical signal processing. Due to it’s highly localization to metallic surfaces, surface plasmon (SP) may have many applications in sub wavelength to guide the optical signal in waveguides to overcome the diffraction limit which considered a big problem in conventional optics. The proposed design of MIM structure is consist of a dielectric waveguides plus metallic claddings, which guide the incident light strongly in the insulator region. Strong localization and relatively simple fabrication make the MIM waveguides the potential key design of Nano-scale all optical devices. Our design consists of symmetric ring structures with straight waveguides which based on MIM structure. All-optical logic gate (NOT gate) behavior is achieved from utilizing the interface between straight waveguides and ring structure waveguides. By switching the activation of the control port, the propagation of the outgoing field in the output waveguide will be changed. As the simulation results show, the proposed structure could operate as an all-optical NOT logic gate. This gate would be a potential component in many applications of all-optical signals processing.

Abstract:
The dispersion properties of surface-type electromagnetic waves propagating along azimuthal angles in circular metal waveguides entirely filled by two layers of plasma in an axial static magnetic field are studied. The three-component structure models plasma radial inhomogeneity and generalizes two research which was two researches which were accomplished earlier. One is a circular metal waveguide entirely filled by cold plasma in an axial static magnetic field. The other is a coaxial metal waveguide entirely filled by plasma. Introducing the additional interface between the plasma column and coaxial plasma layer causes arising of the additional root of the dispersion relation which can be of interest for practical applications. The disappearance of additional wave branches with decreasing the difference in the plasma particle densities is carefully investigated. The wave dispersion properties are demonstrated to be mostly determined by the plasma with smaller particle density.

Abstract:
Abstract The main objective of this thesis was to research the integration of novel materials and fabrication processes into Low Temperature Co-fired Ceramic (LTCC) technology; enabling fabrication of Radio Frequency (RF) and microwave components with advanced performance. The research focuses on two specific integration cases, which divide the thesis into two sections: the integration of tunable dielectric structures and the integration of air filled waveguides. The first section of the thesis describes the development and characterization of low sintering temperature Barium Strontium Titanate (BST) thick film paste. Sintering temperature of BST is decreased from approximately 1350 °C down to 900 °C by lithium doping and pre-reaction of the doped composition. This allows the co-sintering of the developed BST paste with commercial LTCC materials. Additionally two integration techniques to embed tunable components in an LTCC substrate using the developed BST paste are also presented and the electrical performance of the components is evaluated. The highest measured tunability value was 44% with a bias field of 5.7 V/µm. The permittivity of the films varied between 790 and 190, and the loss tangent varied between 0.004 and 0.005, all measured unbiased at 10 kHz. The developed LTCC compatible BST paste and the presented integration techniques for tunable components have not been previously published. In the second section of the thesis, a fabrication method for the LTCC integrated air-filled rectangular waveguides with solid metallic walls is presented. The fabrication method is described in detail and implemented in a set of waveguides used for characterization. A total loss of 0.1–0.2 dB/mm was measured over a frequency band of 140–200 GHz. The electrical performance of the waveguides is evaluated and their use demonstrated in an integrated LTCC antenna operating at 160 GHz.

Abstract:
A method to measure the reflectivity of laser mirrors and to determine optical losses of laser elements Such as windows, capillaries and especially waveguides including slab waveguides has been developed. Measurements have been carried out using a Scanning-Fabry-Perot-Interferometer wind, forms a stable optical resonator and creates thereby laser-like conditions. One mirror is movable by a circular arrangement of piezo elements to tune resonator length by several laser wavelengths. Laser power is coupled into the interferometer and power transmitted through or reflected by the interferometer can be described by Airy-functions. Both values are functions of interferometer length and depend on optical losses within the interferometer. Evaluating measured Airy-curves enables the determination of losses in stable resonators, in waveguide resonators, and also in hybrid slab-waveguide resonators, the latter using cylindrical mirrors. The reflec- tivity of different laser mirrors, the optical losses of alumina ceramic and copper waveguides and coup bug losses were determined for different wavelengths between 9.2 µm 10.8 µm The standard deviation is about 1% of resonator losses. Losses of ceramic-waveguide resonators have been measured for different mirror-waveguide gaps, varying mirror tilt-angles and with apertures placed close to the mirror. Measured optical losses show some minima and maxima at different mirror-waveguide distances. Moreover, it was observed that an aperture placed between the waveguide and the mirror can reduce measured losses.

Abstract:
Narrowband (<10Å) optical multiplexer/demultiplexers are important components for densely spaced wavelength division multiplexed systems. Waveguide grating reflectors provide an excellent basis for such devices.1,2 This contradirectional interaction provides narrowband response even for relatively short interaction lengths (< 1 mm). However, the wavelength dependent Bragg reflection within a waveguide is, by itself, not sufficient to act as a multiplexer/demultiplexer component. Spatial, not just directional, separation, of the filtered light is also required. Two techniques to efficiently provide such spatial separation in grating-based devices have been suggested. One approach, which employs a grating to achieve phase matched contradirectional coupling between mismatched waveguides has been achieved, with relatively low efficiency, in fiber couplers3 and with vertical couplers based on ARROW waveguides.4 Another possibility, well-known in the microwave domain, combines the bandpass reflectors on both output arms of a broadband 3 dB splitter.5,6 Here we report the first demonstration of this optical waveguide grating-folded coupler to achieve narrowband, spatially isolated wavelength demultiplexing. This approach has the advantage of not placing severe demands upon either the waveguides or grating.

Abstract:
GaAs optoelectronic integrated circuit (OEIC) technology is having an increasing impact in the areas of communications and signal processing, with applications such as high speed broad-band switching, high-speed interconnects for multiprocessor local area networks (LANs) and optically controlled phased-array antennas. A major component of the production of OEICs is the low cost, robust and reliable integration of optoelectronic devices for generating, amplifying and detecting optical signals. Recently, there has been considerable interest in the integration of photodetectors with optical waveguide circuits. Monolithic integration of metal-semiconductor-metal (MSM) detectors with semiconductor optical waveguides has been achieved by evanescent coupling from a waveguide layer into an absorbing detector layer grown epitaxially on top of the waveguide1,2. In this paper we examine the potential of polyimide waveguides as integrated light distribution systems in monolithic OEICs. Polymer guides can be formed on top of complex semiconductor circuitry by spin coating and photolithography. Polymer waveguides offer the advantages of ease of processing, low cost, and low optical losses. As well, vertical coupling facilitates alignment of light sources and detectors without additional components such as gratings or 45° facets.

Abstract:
The advance of integrated-optics technology has increased interest in guided-wave phenomena. The problem of coupling between parallel dielectric waveguides has been extensively studied. However, the previous discussions are made only for the coupling of a single-frequency wave. In this research, we investigate the problem of conversion of a pulse from one waveguide to the other. The pulse is first decomposed into different frequency components. The coupling between waveguides for each component can be evaluated by using the well-developed coupling theories. The coupled pulse is simply a superimposition of many coupled components. Because the coupling coefficients for various frequency components are different, the coupled pulse is distorted. These distortions are examined for both TE and TM modes. A two-waveguide system is discussed first. Then, a system with more than two parallel waveguides is studied. Also, in evaluating the coupling strength, the conventional coupling formalism is used. However, the modified theory by Streifer is considered as well.

Abstract:
The quantum mechanical wave behavior of ballistic electrons allows them to be guided by a semiconductor quantum well. These structures act as optical slab waveguides for guiding directions normal to the confinement direction. The allowed modes in an asymmetric quantum well slab waveguide are described quantitatively. Electron waveguiding can occur for energies above one or both of the potential barriers. Due to dispersion, each electron waveguide mode has an upper-energy cutoff as well as a lower-energy cutoff. An example waveguide consisting of Ga0.85 Al0.15AS (substrate), GaAs (film), and Ga0.70 Al0.30AS (cover) is presented. For [100] GaAs layer thicknesses of from six through thirty-one monolayers this structure is a single-mode electron waveguide. These waveguides are potentially useful in high speed electronic circuitry and as a central component in future electron guided-wave integrated circuits.
