I grew up as, and ever will be, a Los Angeles Dodgers city-girl, but currently I attend the University of California, San Diego as nano-engineer. I find the electron to be the most curious object in the world and certainly worthy of devoting a lifetime to its study. I am very interested in applying the fundamental branches, or “logics”, of quantum computing and seeing where their nodes meet locally, or totally, for technological/medical application. Therefore, my goal is to experimentally begin with a elucidating and merging its software (correlation/concurrence, discrete physics, quantum algorithms, LRD/data mining) with hardware (optical microelectromechanical systems, advanced silicon photonics, nonlinear optics on a chip).

We analyze lithographically defined nanophotonic bragg reflectors around 1550nm. Creation of high extinction resonators is important for applications from quantum key distribution to photonic addressing of trapped atomic ions for quantum information processing. Bragg reflectors are desirable for the creation of high quality filters and resonators due to their easily tailored reflection strength and bandwidth. We use a hybrid silicon nitride on lithium niobate material platform with corrugated waveguides to support a first order Bragg resonance. The integration of these structures in an electro-optic material such as lithium niobate allows such resonators to be used as tunable structures such as modulators, part of our future work. Devices with both rectangular and sinusoidal index variation are analyzed. Spurious reflections and unexpected resonances are seen in experimental transmission profiles. Discussion of possible mechanisms for these unintended resonances are discussed. We explore the application of such resonators for photonic addressing of trapped ions.
