Title : Adding Functionality to Cavity Optomechanical Systems
Abstract : Coupling between optical and mechanical modes has enabled a wide variety of interesting potential applications, including sensors, mode converters, reference oscillators, and quantum systems. Increased sensitivity in these systems results from the fact that optical interferometry is perhaps the most sensitive and high-bandwidth method for reading out motion, and cavity optomechanics allows for this to be done in a compact, stable system. In this talk, we will explore the optomechanical performance of microrings implemented in a variety of materials, focusing on their potential as low-phase-noise, on-chip reference oscillators with electrostatic tuning functionality. We will also present GHz-frequency optomechanical crystals in stoichiometric silicon nitride, including techniques for improving their optomechanical performance and versatility through design and fabrication.
