The Effects of Multi-exciton Interactions on Optical Cavity Emission
Qi, Xiaodong (2012-07-31)This thesis presents a theoretical study of the collective effects of a large number of photon emitters coupled to optical cavities. The ensemble effects are accounted for by considering both the light emitting and ... -
Excitonic Analysis of Many-Body Effects on the 1s−2p Intraband Transition in Semiconductor Systems
Parks, Andrew Marshall (2011-06-06)I present a detailed study of many-body effects associated with the interband 1s transition and intraband 1s-2p transition in two- and three-dimensional photo-excited semiconductors. I employ a previously developed excitonic ... -
An Excitonic Approach to the Ultrafast Optical Response of Semiconductor Nano-Structures
Wang, Dawei (2008-12-02)In this thesis, I present an excitonic approach to treating the coherent dynamics of optically generated charge carriers in semiconductor nanostructures. The main feature of this approach is that it includes exchange ... -
Nonlinear Response of Unbiased and Biased Bilayer Graphene at Terahertz Frequencies
McGouran, Riley (2016-03-31)The main focus of this thesis is the investigation of the nonlinear response of unbiased and biased bilayer graphene to incident radiation at terahertz frequencies. We present a tight-binding model of biased and unbiased ... -
The optical properties of metamaterial waveguide structures
Reza, Arvin (2008-11-04)Metamaterials, artificially engineered structures with negative average relative permittivity and permeability, provide a route to creating potential devices with exciting electromagnetic properties that cannot be obtained ... -
Quantum Nonlinear Optics in Lossy Coupled-Cavities in Photonic Crystal Slabs
Kamandar Dezfouli, Mohsen (2015-06-02)A general formalism is developed that can be used to obtain photon dynamics in coupled-cavity system in leaky photonic crystal slabs. This is accomplished using a non-Hermitian projection operator, where the coupled-cavity ... -
Quantum Optics and the Quantum Jump Technique for Lossy and Non-Orthogonal Systems
Doutre, Sean (2013-09-28)In this thesis I develop a formalism for analyzing quantum optics in photonic crystal slab cavities which may be coupled, lossy, and non-orthogonal. Using a tight-binding approximation I find classical coupled-cavity ... -
Terahertz driven intraband dynamics of excitons in nanorods
Sy, Fredrik (2014-05-15)Quantum dots and nanorods are becoming increasingly important structures due to their potential applications that range from photovoltaic devices to medicine. The majority of the research on carrier dynamics in these ... -
Terahertz Response of Excitons in Nanorod Heterostructures
d'Eon, Ryan (2016-05-19)Quantum-confined systems are one of the most promising ways to enable us to control a material's interactions with light. Nanorods in particular offer the right dimensions for exploring and manipulating the terahertz region ... -
Tight-Binding Approximations in 1D and 2D Coupled-Cavity Photonic Crystal Structures
Day, C. L. Nicole (2016-06-07)Light confinement and controlling an optical field has numerous applications in the field of telecommunications for optical signals processing. When the wavelength of the electromagnetic field is on the order of the period ...
