Full textOur research is concerned with the optical response of nano-structures by modeling them in order to enhance the confinement of light in these structures, which leads to the exaltation of linear and nonlinear optical effects.Our work is divided into two sections, which are based on the enhancement of the electric field inside the structure. In the first section, we study the optical properties of a Bowtie Nano-aperture, BNA, as a function of the refractive index of the surrounding medium. The study discusses the variation of the resonance wavelength and the intensity of the enhanced field in the gap of the BNA as a function of the distance from a sample placed in front of our BNA. The BNA is engraved at the apex of a metallic coated fiber tip. In this section a theoretical study was achieved using the Finite Difference Time Domain method FDTD in which we implement a Drude dispersion model to faithfully describe the optical properties of metals. In addition, a validating experimental study was achieved and a high accordance between both results is recorded.In the second section, the electro optical effect of nano-structures is studied. Electro-optical effect or Pockels effect is the variation of the refractive index of a nonlinear media as a function of an applied external electric field. The electro-optical effect is a linear variation of the media refractive index. However it is also related to the second order nonlinear susceptibility tensor, thus it becomes a nonlinear effect that only occurs in non-centrosymetric material. In our study we chose the case of a nano-structure fabricated with Lithium Niobate. Lithium Niobate is widely used in photonic applications due to its electro-optical, acousto-optical and nonlinear optical properties. We present a theoretical study of the electro-optical effects using the FDTD simulation method. We started by approving the ability to use the FDTD to calculate the refractive index variation in bulk Lithium Niobate then we suggest different approximations to estimate the refractive index variation when the light is confined inside the structure. In addition we suggest a new self-consistent method in which the variation of the refractive index is modified during the simulation. The study shows a comparison between different assumptions (used in previous research) and the self-consistent method for various structures, like Bragg reflectors, cavity structures and 2D photonic crystals. The study shows that the difference between the results of each assumption becomes greater when the optical confinement in the structure becomes more important

As the development of optical data storage, the demand for higher data storage capacity inspires researchers to produce the tiny and intense light spot. The nano-probe is widely used to confine the input light into the small area at the near field. The main issue lies in its low throughput. The Bethe’s formula provides a clear physical insight to the nano-aperture. When the aperture size on an infinitely thin and perfectly conducting film is much smaller than the incident wavelength, the transmission of the circular aperture is ~ (d/λ)4. The mechanism of nano-aperture is divided into three parts: (1) photon capture ability determined by the entrance geometry, (2) energy transportation influenced by the film thickness, and (3) the exit radiance distribution. Based on the prior literature, we designed a composite aperture to keep the intense throughput and the tiny spot at the same time. The metal surface in the vicinity of the aperture is corrugated to supply horizontal momentum and induce the “extended surface plasmonic resonance”, which results in the further enhancement of the transmission. Our proposed corrugated composite aperture was able to enhance power throughput by ~200X compared with the comparable square aperture.

In recent years, the studies about extraordinary transmission through subwavelength metallic aperture have drawn more attention, called surface plasmon. These researches included subwavelength metallic hole array, single subwavelength metallic aperture, and an aperture with periodic corrugations array by T.W. Ebbesen et al.. As in 2004, L. Hessenlink et al. designed C-shaped aperture with not only spot size to ��/10 but the power throughput enhancement can achieve to ~103. Meanwhile, M. Mansuripur et al. used FDTD method to simulate the enhancement and field distributions in 2-D slit aperture. This thesis aims to analyze the subwavelength metallic aperture in visible range (especially at ��=633 nm), and the connection of the special apertures. Base on the phenomena we observed, try to give a composite structure which could take both advantages of high transmission and small spot. The researches might be applied in super resolution spot in optical data storage system.

We propose a novel metallic nano-bowtie aperture with projected pad underneath (BAPPU) with localized surface plasmon resonance (LSPR). In this structure, the bowtie aperture induces strong near-field in the gap region owing to coupling effect and lightning effect. In addition, our proposed BAPPU structure can be realized via simplified fabrication process, which make fabricating it on fiber-tip possible and useful in biologic and chemical sensing. In experiments and simulations, we found that there are two significant LSPR modes, fundamental and high order modes, in BAPPU structure. The fundamental mode processes stronger field intensity because of its powerful dipole moment. In addition, for the fundamental mode, via geometry tuning, we also investigate the dependence of gap distance, length, and width on resonance wavelength and charge distributions. Furthermore, we also investigate the capabilities of BAPPU in optical sensing, wavelength tuning, and nanoparticle trapping. In optical index sensing, high sensitivity of 1620 nm/RIU is observed. 1620nm/RIU;In addition, by embedding bowtie pad within PDMS, wavelength tuning via stretching is achieved. In the simulation of optical trapping via BAPPU with 30 nm gap distance, the optical force is as high as 7989 pN/W for trapping 20 nm polystyrene particle. Therefore, we believe our proposed BAPPU can achieve versatile on-fiber probe and optical manipulator.

For near-field optical systems, Aperture and Solid Immersion Lens(SIL) that are popular techniques can overcome light diffraction limit and reduce spot size. According to previous researches, nano-aperture combined with SIL can improve the throughput owing to greater power densities at the aperture and reduce spot size to nano grade. However, the misalignment between the SIL and nano-aperture always occurred in assembling or bonding step. Earlier academic advanced a self–alignment technique to overcome the misalignment. But the method lack practical application in optical systems. In this thesis, the supporting structure can solve the problem. In fabrication results, the supporting structure can be made accurately. About nano-aperture ,100nm、200nm and 300 nm aperture are fabricated and the maximum error is less than 5% in comparison with the designed values. The SIL also can be made successfully. From the measurement results of far-field system, manifest that SIL can reduce spot and the 15μm-diameter SIL/300nm-diameter circular aperture component has 1.216 times enhancement of transmission compared with 329nm-diameter aperture alone. Basing on the measurement results, the supporting structure make the SIL and nano-Aperture more feasible.

For near-field recording systems, Aperture and Solid Immersion Lens(SIL) are two popular techniques to overcome light diffraction limit and reduce spot size. In aperture systems, seeing that light spot size is directly determined by aperture size, aperture systems can provide an ultra-high resolution by reducing the aperture size to nano-scale. However, nano-aperture suffers from low power throughput which results in the recording speed unable to be promoted. SIL systems, while can providing a smaller spot size than obtained in conventional optical recording systems with still maintaining high optical throughput, do not have the resolution observed from aperture probe systems. According to previous researches, nano-aperture combined with SIL/SSIL can improve the throughput owing to greater power densities at the aperture. However, the misalignment between the SIL/SSIL and nano-aperture always occurred in assembling or bonding step. How to align the nano-aperture and SIL/SSIL together precisely has not proposed yet. In this research, the purpose is concentrated on combination of SIL/SSIL and nano-aperture by Nano/Micro Electro-Mechanical Systems(N/MEMS) technology, where nano-aperture is fabricated with Focused Ion Beam(FIB)system and SIL /SSIL are formed by thermal reflowing process. In order to overcome the misalignment between SIL/SSIL and nano-aperture, a self-alignment technique based on self-modulation by surface tension during thermal reflowing process is proposed. About aperture designs, the influence of varied shapes of apertures at optical throughput is also studied. Here, circular apertures and C-shaped apertures are introduced. In fabrication results, SIL and SSIL are fabricated and the maximum error is less than 3% in comparison with the designed values. About nano-aperture, the diameter 103nm, 148nm, and 329nm of circular aperture and the dimensions 303nm×205nm and 223nm×105nm of C-shaped apertures are fabricated. The feasibility of self-alignment technique between SIL/SSIL and nano-aperture proposed in this research is also verified by Scanning Electron microscope(SEM). From the measurement results of far-field system, the 15μm-diameter SIL/329nm-diameter circular aperture component has 1.68 times enhancement of throughput compared with 329nm-diameter aperture alone. This result shows that SIL can really enhance the light throughput of nano-aperture and the feasibility of self-alignment technique between SIL and nano-aperture is further verified. About measurement results of C-shaped apertures, the throughput of 303nm×205nm C-shaped aperture alone is 14.325 times larger than that of 148nm-diameter circular aperture alone, while maintaining a comparable near-field spot size. Even the throughput of 303nm×205nm C-shaped aperture/15μm-diameter SIL component can be enhanced by 24.438 times as compared with 148nm-diameter circular aperture alone. This result indicates that combination of SIL and C-shaped aperture can really greatly enhance the performance of near-field pick-up head.
