Among the 62 new SPIE Fellows this year are 10 from Asia: nine distinguished academic researchers and a lithography pioneer from Nikon who are recognized for scientific and technical achievements in optics and photonics and for their service to SPIE.

These 10 Fellows from China, Japan, Taiwan, and India have published thousands of innovative research papers in optomechatronics, silicon photonics, smart structures, photovoltaics, biophotonics, agri-photonics, nanophotonics, immersion lithography, liquid crystals, plasmonics, and other technologies. One is a member of the People’s Congress in China, another developed the first tunable liquid crystal laser, and a third is an educator and entrepreneur who co-founded a semiconductor factory in China. Three are deans of prestigious universities.

All active members of SPIE, they serve as referees and editorial board members on SPIE journals and are involved with the technical programs at SPIE conferences throughout the world.

SPIE Professional is highlighting the achievements of several groups of new SPIE Fellows throughout the year in both print and online. For a complete list of SPIE Fellows, go to spie.org/fellows.
