Micro/Nano-Photonics Research Laboratory
* Advanced optical micro/nano-fabrication technologies
Conventional nanofabrication technologies, such as electron beam (EB) or focused ion beam (FIB) lithography, are commonly expensive and low yielding. Emerging photonic/biomedical microdevices, however, demands flexible micro/nano-fabrication technologies for efficient processing of different materials. Using UV laser sources, our group is developing advanced optical micro/nano-fabrication technologies, such as digital UV lithography, precision photoreduction, and optical 3D µ-printing, for development of functional devices, sensors and microsystems.

* Micro/nano-photonic structures, devices, and applications
Using our own-developed optical micro/nano-fabrication platforms, we endeavor to integrate photonics, functional materials, bio/nano-technologies to solve emerging problems whose solutions are beyond the scope of single research discipline. Our ultimate goal is to fuse photonics and optoelectronics with functional bio/nano-materials to develop high value-added photonic and biomedical devices and chips, such as plasmonic biosensors, optomechanical microresonator sensors, lab on a chip and optofluidic chip devices.

* Optical fiber-based devices, lasers, and sensors
Optical fiber technology has become an indispensable building block in sensors, lasers, and communication systems. Using the own-established fiber-grating fabrication and optical 3D µ-printing platforms, our research team is developing a) novel optical fiber sensors and b) fiber laser sources and oscillators. Innovative micro/nano-photonic structures will be fused with versatile optical fibers to harness lightwave technologies for sensor and device development.
