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.

Nanophotonic molecules explore the linear coupling of light between neighboring optical microresonators to control spectral properties and spatial light distribution. These devices have been extensively studied for optical signal processing, ranging from optical multicasting to nonlinear frequency conversion. More recently, research led by the Del'Haye group has demonstrated promising opp…
