• Post Doctoral Research Scholar

  • May 2011 - Jan 2015

  • Demonstrated advanced polarization holograms for a wavefront reshaping utilizing novel polarization holography and liquid crystal technologies.• Designed and demonstrated novel polarization conversion systems that can produce polarized light from un-polarized light with high efficiency.• Demonstrated a prototype Pico-Projector containing a polarization converter and a LCoS micro-display with diffractive elements, which is more compact, energy efficient, and cheaper than other conventional approaches.• Supervised and assisted an international team for a mass production of new diffractive elements and for a commercialization of the Pico-Projector coordinated with GreenLight Optics, USA., Cordic Technology, Taiwan, ColorLink, Japan, etc.• Designed and developed new lithographic techniques for fabricating polarization sensitive diffractive elements using rotating grating masks. These new approaches have significant impact on robust and easy fabrication of the elements.• Peer-review activitiesJournal reviewer for Optics LettersJournal reviewer for Optics ExpressJournal reviewer for Applied OpticsJournal reviewer for IEEE Photonics JournalJournal reviewer for IEEE Photonics Technology LettersJournal reviewer for IEEE Journal of Lightwave Technology Journal reviewer for Optical MaterialsJournal reviewer for Optical EngineeringJournal reviewer for Optical CommunicationsJournal reviewer for Mathematical Problems in Engineering Journal reviewer for Journal of Applied Mathematics
