Abstract:

Two dimensional photonic crystals (2D PhCs) in a GaAs/AlGaAs environment were studied experimentally. Emphasis was placed on evaluating the loss characteristics of these structures. Fabrication of 2D PhCs was carried out using a combination of electron beam lithography, reactive ion and electron cyclotron resonance etching techniques. This work was carried out at the Sharp Laboratories of Europe. Excellent control over the more than fifty necessary processing steps was demonstrated and further improvements suggested. An optical laser-based characterization experiment was set up to study the tr

Abstract:

In this dissertation, we study the optical property of 2D graded photonic super-crystals (GPSCs) for photon management. We focused primarily on manipulation and control of light by using the newly discovered GPSCs which present great opportunity for electromagnetic wave control in photonic devices. The GPSC has been used to explore the superior capability of improving the light extraction efficiency of OLEDs. The enhancement of extraction efficiency has been explained in term of destructive interference of surface plasmon resonance and out-coupling of surface plasmon through phase matching pro

In this dissertation, I am presenting my research on the fabrication and simulation of the optical properties of 3D photonic crystals and 2D graded photonic super-crystals. The 3D photonic crystals were fabricated using holographic lithography with a single, custom-built reflective optical element (ROE) and single exposure from a visible light laser. Fully 3D photonic crystals with 4-fold, 5- fold, and 6-fold symmetries were fabricated using the flexible, 3D printed ROE. In addition, novel 2D graded photonic super-crystals were fabricated using a spatial light modulator (SLM) in a 4f setup for

The topic of this dissertation is photonic crystal nanocavities for semiconductor cavity quantum electrodynamics. For the purposes of this study, these nanocavities may be one dimensional (1D) or two dimensional (2D) in design. The 2D devices are active and contain embedded InAs quantum dots (QDs), whereas the 1D devices are passive and contain no active emitters. The 2D photonic crystal nanocavities are fabricated in a slab of GaAs with a single layer of InAs QDs embedded in the slab. When a cavity mode substantially overlaps the QD ensemble, the dots affect the linewidths of the observed mod

Photonic clystals are an exciting component in the field of nanophotonics. They allow the control, confinement and manipulation of light at the nanometre scale. The ability to fabricate photonic clystals with semiconductor fabrication technology makes them a suitable building block of photonic integrated circuits. Photonic clystals offer sensitivity to surrounding materials and they can enhance light-matter interaction.

2D-Photonic crystal (PC) structures have enabled the fabrication of a wide variety of nanophotonic components. In perfect PCs, the exploitation of the enhanced local density of states at critical points of the band diagram has attracted considerable attention. Near these points, where the group velocity vanished, low curvature flat bands give rise to delocalized and stationary optical slow Bloch modes (or slow light modes). Properties of slow light make them good candidates to enhance Purcell or various non-linear effects or to design low-threshold lasers. Among these modes, slow Bloch modes (

The manipulation of photons, especially the control of spontaneous emission, has become a core area of photonics research in the 21st century.

Recently, attention has focused on resonant nanophotonic structures to control the thermal emission with most of the work concentrating on the mid-infrared wavelength range and/or based on metallic nanostructures. However, the realisation of a high temperature, single wavelength, narrowband and efficient thermal source, remains a challenge. In this project, f

Abstract:

碩士<br>國立交通大學<br>光電工程系所<br>97<br>In this thesis, we investigated the different lasing behavior of GaN-based 2D photonic crystal surface emitting lasers (PCSELs) according to different photonic crystal (PhCs) lattice constant. Based on the Bragg theory for PhCs period structure, the lasing behavior could only happen when the Bragg condition is satisfied. Therefore, we simulated the band diagram of TE mode by plane wave expansion method, designed the PhCs lattice constant ranging from 190 to 230 nm, and fabricated the PhCs period structure on our novel GaN-based resonance cavity light emitting di

Abstract:

碩士<br>國立臺灣大學<br>物理研究所<br>94<br>In recent years, with growing interests to Photonic Crystals (PhCs) and their applications, many researchers have studied PhCs. 2-Dimensional PhC laser is one of the interesting research topics due to its strong light confinement in a small wavelength-scale volume. Liquid Crystal (LC) infiltrated 2D PhC laser has also been investigated for the laser wavelength tuning, yet its theoretical study seems insufficient. Thus, in this research, we developed 3D Finite-Difference Time-Domain (FDTD) program which can simulate the light propagation in LCs, and analyzed the

Abstract:

碩士<br>國立臺灣大學<br>電機工程學研究所<br>95<br>This thesis describes an approach to fabricate a 2-dimensioinal photonic crystal waveguide by combining near-field phase-shifting contact lithography and interference lithography. The elastomeric phase mask is fabricated by casting and curing the prepolymer of PDMS (Polydimethylsiloxane) against photolithographically patterned lines of photoresist on a silicon substrate. We then expose the UV light through the elastomeric phase mask onto the photoresist to perform photolithography in the near field of the mask for fabricating the 2-dimensional photonic cry
