Research Synopsis: Our research is conducted at the convergence of two central areas of nanotechnology-nanophotonics and nanomechanics. We develop nano-electro-mechanical systems (NEMS) and nano-opto-mechanical systems (NOMS) to explore their novel properties in both classical and quantum regimes. We study the coupling and interaction between the optical, electrical, magnetic and mechanical degrees of freedom (i.e. photons, electrons, spins and phonons) in nanoscale devices. We employ state-of-the-art top-down or bottom-up approaches to fabricate devices and structures with various semiconductor and dielectric materials. We utilize integrated photonic circuits as optical breadboards to investigate and exploit the optoelectronic properties of novel materials including 2D crystals, magnetic and quantum materials. Our interest spans from the measurement of fundamental physics parameters with the highest precision that is only bounded by the law of nature, to development of novel devices for radio-frequency, microwave and optical communication and computation, and to building tools for chemical and biomedical sensing, medical diagnostics and neuroscience.
