Abstract:

Because of their compatibility with the planar concept of integrated optics, grating couplers offer the most satisfactory means of coupling light into thin film optical waveguides. The purpose of this dissertation has been to study the behaviour, both theoretically and experimentally, and fabrication of grating couplers in nonlinear waveguides. A theory of nonlinear grating couplers is presented based on a coupled-mode approach. The dependence of coupling efficiency on incident beam intensity, beam size, beam position, incident angle, chirp rate, and waveguide losses have been examined all in

Abstract:

This dissertation formulates and applies a theory describing how one or two strong classical waves and one or two weak quantum mechanical waves interact in a two-level medium. The theory unifies many topics in quantum optics, such as resonance fluorescence, saturation spectroscopy, modulation spectroscopy, the build up of laser and optical bistability instabilities, and phase conjugation. The theory is based on a quantum population pulsation approach that resembles the semiclassical theories, but is substantially more detailed. Calculations are performed to include the effects of inhomogeneous

Abstract:

The optical stretcher (OS) is dual-beam laser trap capable of capturing and deforming micron-sized particles or biological cells. It can be employed to measure cell-mechanical properties and, thus, to monitor physiological changes, such as differentiation, and to diagnose diseases that affect the structural integrity of cells, like cancer and sickle-cell anemia. To correctly interpret the deformation data, this study presents a versatile physical framework for the electrodynamics, mechanics, and thermodynamics in the OS. Due to the limitations of geometrical optics (GO), an analytical approach

Abstract:

A theory, based on material parameters, is developed for colloidal-crystal Bragg filters. The coupling constant, for coupled-wave equations, is derived to produce filter spectra. The spectra are modified by convolving with a Gaussian function to represent crystal defects. Scattering losses are calculated to attenuate the out-of-band transmission. The theory is tested by comparing theoretical spectra with experimental spectra from colloidal-crystal Bragg filters fabricated with polystyrene and poly(methyl methacrylate) colloid spheres. A novel cell, for containing the colloidal crystal, is pres

The objective of this thesis is to develop the quantum theory of the motional degrees of freedom of a charged particle in a Penning trap.

The quantum form of the experimental techniques of sideband coupling and driving to the ultra-elliptical regime are examined in this context, and resulting future applications considered.

Abstract:

Two spectral regions of gain exist for a weak probe beam propagating through a medium of two-level-atoms pumped by a strong near-resonance field. Experimentally a cw ring-dye laser is used to explore this gain at the Na D₂ resonance in a vapor. Plane-wave calculations of probe-gain spectra which include the Doppler broadening inherent in a vapor agree well with experimental spectra obtained with a Fabry-Perot interferometer. Such two-beam-coupling gain might have applications as optical pre- or power amplifiers. The gain is also the primary step in four-wave-mixing. Mixing of the pump and side

This dissertation addresses both fundamental aspects of the coherent exciton kinetics in single semiconductor quantum wells and more application-oriented aspects of the collective excitonic optical properties in quantum well Bragg structures. We use a bosonic theory to investigate the ultrafast coherent exciton dynamics after an optical excitation in a single semiconductor quantum well. It is shown that, on intermediate time scales, nonlinear mean-field interactions between excitons lead to a coherent, wave-like evolution in the momentum distribution of optically inactive excitons, which can s

Abstract:

Within the framework of interacting-electron models, the optical nonlinearity in π-conjugated polymers is investigated theoretically. A complete microscopic many-body theory is developed for the mechanism of the third order nonlinearity in these materials. The universality and the predictability of the theory are well established. It is found that the bulk of the optical nonlinearity in conjugated polymers is determined by four essential states although all the excited states are involved. It is also found that electron-electron Coulomb interactions in one-dimensional systems play key roles in

Abstract:

This dissertation presents theories of multiwave mixing in two- and three-level media. The first part of the dissertation treats the semiclassical theories in two-level media. Chapter 2 gives the simple semiclassical theory of four-wave mixing when the two pump frequences differ by more than the reciprocal of the population-difference lifetime. This difference washes out the pump spatial holes as well as one of the two reflection gratings. We compare the results to the degenerate treatment of Abrams and Lind and find significant differences in the reflection coefficient spectra. Chapter 3 pres

The goal of this dissertation is the derivation of a differential equation that describes the evolution of an electromagnetic field in a stable cavity that has no axial symmetry (a toroidal system).

Optical and electronic properties of semiconductors heterostructures are analyzed, combining many-body and band structure engineering techniques.

In the high density regime, coupled band optical Bloch equations are obtained, combining Coulomb effects with the solutions of the Luttinger Hamiltonian, and the problem is solved in general

There are three fundamental mechanisms in optical systems that contribute to image degradation: aperture diffraction, geometrical aberrations caused by residual design errors, and scattering effects due to optical fabrication errors.

However, these ray-trace codes fall short of providing a complete picture of image degradation; they routinely ignore fabrication-induced errors
