Research in Fang group focuses on study of light-matter interactions and light manipulation 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 and quantum metrology.
Post-Doctoral Research Opportunities
Our group has a postdoc position opening with a preference of experience in experimental quantum optics or optomechanics. Our research is backed by state-of-the-art fabrication facilities including the first and only 150 keV EBL in North America and quantum experiment equipment including dilution refrigerators.
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 (firstname.lastname@example.org) with a complete CV, accompanied by a short paragraph highlighting relevant practical experience and coursework.
Undergraduate Research Opportunities
We welcome undergraduate students interested in photonics to gain research experience in our group. Students should have preliminary course study in electromagnetism, photonics, etc.
