Dielectric micro-cavity surface-emitting lasers
In recent years, various metal-cavity nano-lasers have been theoretically studied and experimentally realized because it is believed that their small sizes can actually bring large potential in the next-generation dense photonic integration and optical interconnects. However, the absorption loss in …

Numerical modelling of optical micro-cavity ring resonators for WDM networks
… ways to improve the performance of optical microcavity ring resonators (MRRs) have been thoroughly investigated and new configurations have been proposed. The Multiresolution Time Domain (MRTD) technique was further developed and employed throughout this thesis as the main numerical …

All-optical processing for terabit/s wavelength division multiplexed systems using two-photon absorption in a semiconductor micro-cavity
… absorption nonlinearity within a resonance cavity enhanced structure is explored within this thesis. High-speed transmission is severely limited by optical impairments requiring frequent and expensive signal regeneration. Chromatic dispersion, considered as one of the main limiting factors, …

One-dimensional photonic crystal / photonic wire cavities based on silicon-on-insulator (SOI)
… PhC structures embedded in PhW waveguide micro-cavities could become essential components for wavelength selective devices, especially for possible application in WDM systems. The high quality factor, Q, and confinement of light in a small volume, V, are important for optical signal …

Fabrication and Characterization of Small Scale Photo-Electro-Chemical Solar Cells
… of a p-type silicon cathode with an etched micro-cavity that houses the zinc chloride electrolyte solution, and the cavity is covered by a sheet of zinc acting as the anode. The cell operates using a semiconductor-electrolyte junction instead of the p-n junction of a conventional solid state …

Strong proton-photon interactions at the single-photon level
… single photon level orchestrated by an optical cavity. We demonstrate an all-optical transistor where one stored 'gate' photon controls the propagation of a 'source' light beam. The system is based on EIT and a highcooperativity cavity. Each 'gate' photon is converted to an EIT polariton and …

MEMS enabled Fabry-Perot cavity for cQED experiments
… to manipulate atoms in a chip require building micro systems on chip that support actuation, alignment control and tunability for each micro component, which requires a significant integration effort. One example of a new experimental technique in atomic physics is the realization of optical …

Low Dislocation Density Gallium Nitride Templates and Their Device Applications
The unique properties, such as large direct bandgap, excellent thermal stability, high μH × ns, of III-nitrides make them ideal candidates for both optoelectronic and high-speed electronic devices. In the past decades, great success has been achieved in commercialization of GaN based light emitting …
