Current Research and Scholarly Interests

I am interested in developing tools and frameworks for engineering and understanding hybrid quantum systems. In particular, I am interested in novel on-chip platforms with applications in quantum information processing, quantum communication, and fundamental research. I work on the design, fabrication, and characterization of nanoscale devices that integrate, on a single chip, superconducting microwave circuits, nanomechanical resonators, and photonic crystals.

    Future quantum networks, in which superconducting quantum processors are connected via optical links, will require microwave-to-optical photon converters that preserve entanglement. A doubly-resonant electro-optic modulator (EOM) is a promising platform to realize this conversion. Here, we present our progress towards building such a modulator by demonstrating the optically-resonant half of the device. We demonstrate high quality (Q) factor ring, disk and photonic crystal resonators using a hybrid silicon-on-lithium-niobate material system. Optical Q factors up to 730,000 are achieved, corresponding to propagation loss of 0.8 dB/cm. We also use the electro-optic effect to modulate the resonance frequency of a photonic crystal cavity, achieving a electro-optic modulation coefficient between 1 and 2 pm/V. In addition to quantum technology, we expect that our results will be useful both in traditional silicon photonics applications and in high-sensitivity acousto-optic devices.
