Single-photon frequency upconversion for long-distance quantum teleportation and communication
… generation, single-photon detection, and frequency translation that preserves the polarization quantum state of the photons are essential technologies for long distance quantum communication protocols. This thesis investigates the application of polarization entanglement to quantum …

Geometric manipulation of light : from nonlinear optics to invisibility cloaks
… by macroscopic Maxwell's equations. One is frequency conversion of such waves using small intrinsic material nonlinearities. We study conversion of an input signal at frequency w1 to frequency Wk due to second or third harmonic generation or four-wave mixing using coupled-mode theory. Using …

Nonlinear and Time-Modulated Metamaterials: Applications at Microwave Frequencies
… including the creation of nonreciprocal devices, frequency conversion, and more. In this dissertation, we explore, investigate, design, and fabricate metamaterials that open new applications for nonlinearity-based and time-varying devices, particularly in the context of enabling potential …

Breaking the Cycle: the Rise and Fall of Conversion Cycle Limited Three-Wave Mixing
… sources. This is because the intensity dependent conversion period of OPA results in asynchronous conversion across the spatiotemporal intensity profiles of the mixing laser fields. We introduce a new method for achieving efficient OPA by using simultaneously phase-matched idler second harmonic …

High-power deep-UV laser for improved and novel experiments on hydrogen
… sufficiently narrow spectral bandwidth for efficient harmonic generation, motivating further development since there is significant interest in frequency doubling and quadrupling these sources to produce coherent blue radiation and deep-UV radiation. Here, we generate coherent, high-power …
