Dr. Chen's group performs interdisciplinary photonics research in laser photonics, 3D lightwave circuits, advanced manufacturing, fiber optics, and nuclear micro-engineering. The group's expertise includes fiber optics, UV and ultrafast laser processing, microfabrication, finite element analysis, nuclear micro-engineering especially in tritium, and miniaturized photonic system integration. Our group is well-equipped, resourceful, friendly, and open for collaboration. 

Laser Manufacturing. Researchers and students in our group explore laser manufacturing research from nanoscales to macroscales. 

  • Design, fabrication, and applications of 3D transformation optical structures using tunable holographic lithography schemes and metal oxide nanomaterials.
  • Ultrafast laser matter interaction and 3D photonics structures fabrications. This research program has yielded a number of exciting outcomes including flexible lightwave circuits in glass substrates, nonlinear optical topologic insulators, all-glass all-optic MEMS structures, and 3D micro-fluidic devices.
  • Adaptive laser beam forming for laser shock peening for additive manufacturing and MEMS devices.
  • Deep UV laser fabrication of fiber optics components.

Laser Photonics. Dr. Chen's group possesses complete expertise in developing field-rugged, compact, and turn-key solid state laser systems from optics design, to mechanic implementation, to electronic hardware and software development.

Fiber Optics. Another major research thrust in Dr. Chen's group is fiber laser and fiber optics. We invent new specialty optical fibers, study new distributed fiber sensing schemes, and explore new fiber sensor applications for fossil energy, nuclear energy, and structural health monitoring. Students in our research group build new ultrafast fiber laser at 1.0, 1.5, and 1.9-m.
