Our group develops cavity optomechanical systems that harness the interaction between confined light (photons) and mechanical motion (phonons). By engineering high-quality (high-Q) optical cavities integrated with mechanically compliant structures, we utilize radiation pressure to precisely control and measure mechanical vibrations at the nanoscale. This enables us to advance precision sensing and explore quantum-mechanical effects in macroscopic systems. We specialize in developing next-generation optomechanical resonators from advanced materials, particularly lithium niobate (LiNbO3) and silicon carbide (SiC). These platforms offer robust mechanical performance with minimal optical loss, paving the way for innovations in precision measurement, signal processing, infrared detection, and quantum technologies.
Lithium niobate supports strong electro-optic, nonlinear, acousto-optic, and photorefractive effects. Thin-film LN enables low-loss waveguides and high-performance modulators, making it a versatile platform for frequency conversion, microwave photonics, and optomechanical coupling.
Silicon carbide combines a wide bandgap, high refractive index, excellent thermal conductivity, and mechanical robustness. Its nonlinearities and quantum defects make it ideal for high-power photonics, nonlinear optics, and quantum optomechanics.
