Research in Fang group focuses on study of light and light-matter interactions at chip-scale, with an emphasis on developing photonic devices for applications in classical and quantum information processing, sensing, and networking. Current research includes:
- Quantum photonics
Optical Nonlinearities are essential for classical and quantum information technologies. We develop photonic integrated circuits using materials with substantial nonlinearities to enable key resources and protocols for classical and quantum applications.
- Optomechanics
Control of phonons–quanta of vibrations–in engineered structures using radiation-pressure force represents an emerging quantum technique for sensing and information transduction. We develop chipscale optomechanical architectures, such as those based on mechanical bound states in the continuum, to enable novel sensing modalities and quantum phenomena.
- Quantum devices
Phonons can couple with disparate physical systems, leading to hybrid quantum platforms that combine the advantage of individual components. With our collaborators, we are developing architectures and techniques to couple mechanical devices with superconducting qubits.
Our lab is involved in two national quantum centers: NSF’s HQAN and DOE’s Q-NEXT.
