Modeling and Analysis of Photonic Crystal Waveguides
In this work, we investigate several aspects of photonic crystal waveguides through modeling and simulation. We introduce a one-dimensional model for two-dimensional photonic crystal fibers (PCFs), analyze tapered PCFs, analyze planar photonic crystal waveguides and one-dimensional PCFs with …

Exact Solutions of Planar Photonic Crystal Waveguides with Infinite Claddings
… investigation of one-dimensional planar photonic crystal waveguides is carried out. These waveguides consist of a dielectric layer sandwiched between two semiinfinite periodic dielectric structures. Using a novel approach, exact analytical solutions for guided modes in such waveguides are …

Theoretical design of photonic crystal devices for integrated optical circuits
In this thesis we investigate novel photonic crystal devices that can be used as building blocks of all-optical circuits. We contrast the behavior of light in photonic crystal systems and in their traditional counterparts. We exhibit that bends in photonic crystals are able to transmit light with …

Optoelectronic and photonic control of single quantum dots
… to produce high quality two dimensional slab photonic crystals operating with a photonic band gap at ~ 900 nm. By placing a quantum dot into an appropriately designed H1 photonic crystal cavity, strong coupling was achieved between the dot and the monopole mode of the cavity. The vacuum Rabi …

Computation & design for nanophotonics
… has made computers a reliable design tool in nanophotonics. Given that almost any 2d pattern can be fabricated at infrared length scales, there exists a large number of degrees of freedom in nanophotonic device design. However current designs are adhoc and could potentially benefit from …

Cylindrical photonic crystals
… thesis, we explore the properties of cylindrical photonic crystal waveguides in which light is confined laterally by the band gap of a cylindrically-layered photonic crystal. We show in particular that axially-uniform photonic band gap waveguides can exhibit novel behavior not encountered in their …

Fabrication of Hollow Optical Waveguides on Planar Substrates
… presents the fabrication of hollow optical waveguides integrated on planar substrates. Similar in principle to Bragg waveguides and other photonic crystal waveguides, the antiresonant reflecting optical waveguide (ARROW) is used to guide light in hollow cores filled with liquids or gases. …

Chip-scale Photonic Devices for Light-matter Interactions and Quantum Information Processing
Chip-scale photonic devices such as microdisks, photonic crystal cavities and slow-light photonic crystal waveguides possess strong light localization and long photon lifetime, which will significantly enhance the light-matter interactions and can be used to implement new functionalities for both …

Analysis and Applications of Microstructure and Holey Optical Fibers
Microstructure and photonic crystal fibers with periodic as well as random refractive-index distributions are investigated. Two cases corresponding to fibers with one-dimensional (1D) radial index distributions and two-dimensional (2D) transverse index distributions are considered. For 1D …

Novel waveguides for terahertz quantum cascade lasers
… and design QCLs. We also review the two main waveguides employed in THz QCLs: the surface plasmon (SP) and the metal-metal (MM) waveguides. We outline the main fabrication steps for both waveguides. Firstly, a novel photonic crystal-based QCL is presented. It comprises a defect line in a …
