Nonlinear optics in titanium dioxide: from bulk to integrated optical devices
(2013-10-18)
In this thesis, we explore titanium dioxide (TiO2) for ultrafast, on-chip nonlinear optics by studying it in bulk, thin films, and in integrated nonlinear optical devices. TiO2's large nonlinear index of refraction (30 ...
Directional Optical Antennas, Wafer-Scale Metasurfaces, and Single Molecule Surface-Enhanced Raman Scattering
(2013-10-17)
Within the field of optics, one of the topics being currently investigated with considerable interest is that of plasmonics, which refers to the use of surface plasmons on metallic nanostructures to manipulate light. It ...
Near-Field Optical Forces: Photonics, Plasmonics and the Casimir Effect
(2013-10-08)
The coupling of macroscopic objects via the optical near-field can generate strong attractive and repulsive forces. Here, I explore the static and dynamic optomechanical interactions that take place in a geometry consisting ...
Integrated filters for the on-chip silicon photonics platform
(2013-10-15)
We investigate the properties of integrated dielectric filters for the purposes of on-chip routing of photons. We started with the use of high quality factor tunable photonic crystal nanobeam cavities and moving on to ...
Plasmonic Cavities for Enhanced Spotaneous Emission
(2013-09-30)
The modification of spontaneous emission, i.e. the Purcell effect, with optical cavities has been highly studied over the past 20 years as one of the most important goals for cavity quantum electrodynamics (cQED). The ...
Mid-Infrared Photonics in Silicon
(2013-09-18)
The mid-infrared wavelength region (2-20 µm) is of great utility for a number of applications, including chemical bond spectroscopy, trace gas sensing, and medical diagnostics. Despite this wealth of applications, the ...
Nanophotonic Structures for Coupling to Quantum Emitters in the Visible
(2013-09-04)
This thesis is about the design, fabrication, and characterization of nanophotonic elements in the visible that can enhance light-matter interaction for single quantum emitters. We focus on two material systems: single ...
Manipulating Light on Wavelength Scale
(2013-09-18)
Light, at the length-scale on the order of its wavelength, does not simply behave as "light ray", but instead diffracts, scatters, and interferes with itself, as governed by Maxwell's equations. A profound understanding ...
