This project focuses on exploring and enhancing the capabilities of degenerate optical parametric oscillators (DOPOs) in microring resonators, with a specific emphasis on random number generation (RNG) and the generation of squeezed light states.Fabricated near-field coupled silicon nitride microcavities, also known as photonic molecules, were tailored to operate in the normal group veloc…
This proposal involves the investigation of linear and nonlinear phenomena in micro- nano-optical cavities and waveguides; the understanding of the limiting effects of each material, the understanding of the interaction between matter and light, including spontaneous and stimulated emission and the coupling between light, matter, and mechanical degrees of freedom in these structures. Also…
The recent development of active and passive photonic components has revolutionized spectroscopy techniques, compact sources of light of high coherence, data transmission and even redefined the optical computing paradigm. In this proposal we aim to explore the collective and multimodal behavior that appears in optical microcavities as a consequence of nonlinear effects of electronic and m…
The advancement of the nanophotonics research in the past decade have shown its potential to establish disruptive technology in the fields of telecom, multi-core processors and radio-frequency signal proces- sing. In this project we propose the development of on-chip nanophotonic devices based on silicon and III-V materials. Our focus will be two-fold, the coupling between mechanical and …
Nanophotonic devices have been explored as a compelling platform for all-optical quantum information and computational applications. In this work, we engineer group velocity dispersion with on-chip coupled microresonators to enable and optimize diverse optical nonlinear processes. In special, we harness degenerate optical parametric oscillation for quantum random number generation. (AU)

This project focuses on studying third-order nonlinear processes occurring in optical microcavities. The main objective is to explore the generation of optical parametric oscillation, with a specific emphasis on degenerate, dual-pumped, parametric processes. We aim to explore the generation of non-degenerate optical parametric oscillation for the purpose of generating binary phase states.…
The study of nonlinear optical phenomena in micro and nano-scale engineered cavities and waveguides present opportunities to further improve our fundamental understanding of such processes as well as to design new practical devices [29]. This is due to two basic advantages: first, the ability to confine optical waves in the sub-micron scale greatly reduces the optical power required to in…
