Research in Fang group focuses on study of light-matter interactions at micro- and nano-scales. Guided by exploratory theories, research emphasis is given to device demonstrations and multi-scale integrations for applications in photonic quantum information processing, quantum sensing, and quantum networks.
Graduate Research Opportunities
We welcome highly motivated students to join our group. Our research intersects with several fields of science and engineering including quantum optics, nanophotonics, and NEMS, and offers rich opportunities for graduate researchers to be trained in device physics, fabrication, and measurements. Incoming or interested students should contact Prof. Fang (email@example.com) with a complete CV, accompanied by a short paragraph highlighting relevant practical experience and coursework.
