Ultrahigh-Q silicon resonators in a planarized local oxidation of silicon platform

We describe a platform for the fabrication of smooth waveguides and ultrahigh-quality-factor (Q factor) silicon resonators using a modified local oxidation of silicon (LOCOS) technique. Unlike the conventional LOCOS process, our approach allows the fabrication of nearly planarized structures, supporting a multilayer silicon photonics configuration. Using this approach we demonstrate the fabrication and the characterization of a microdisk resonator with an intrinsic Q factor that is one of the highest Q factors achieved with a compact silicon-on-insulator platform.

Ultra-high Q silicon resonators in planarized LOCOS

We describe a modified local oxidation of silicon process as a platform for the fabrication of waveguides and ultra-high Quality factor (5.3) silicon resonators, with nearly fully planar interface for multilayer silicon integration.

Light matter interactions in a hybrid nanophotonic-atomic platform

We demonstrate variety of light matter interactions in our nanophotonic-atomic hybrid system, considering both plasmonic and guided mode interaction with hot vapor.

Frequency locked cascaded micro ring resonators enabling real time and highly precise long and short time sensing

We demonstrate an ultrasensitive differential sensing apparatus, based on a frequency locked cascaded micro-resonator scheme. By measuring the lasers beat frequency a highly sensitive sensor both in short (seconds) and long (hours) times is demonstrated.
