curriculum vitae of, Yoshiyasu UENO


Yoshiyasu Ueno received Master’s degree in Physics (Univ. of Tokyo, 1987), joined NEC Corporation (1987), stayed as a visiting researcher for fundamental research about one year in CREOL, University of Central Florida (1995), received PhD degree in applied physics for his original works in the AlGaInP laser research (Univ. of Tokyo, 1998), and joined the National University of Electro-Communications, Tokyo (associate professor since 2002, and professor since 2009).

In his original university’s master’s course in 1985-1987, he studied the exciton-resonant second-order optical processes in uni-axial, red direct-bandgap semiconductor, HgI2 crystals (bandgap energy of about 1.8 eV), at the liquid-Helium temperature, 4K.

In 1987-1994 with his senior and junior colleagues in the NEC’s research center, he developed a 30-mW high-power 680-nm single-transverse-mode MOVPE-grown-AlGaInP laser design and was engaged in technical transfers of the research results to its mass-production division, for use in optical DVD recorder’s optical pickups in the consumer market.

Since 1995 through present, he started trying to pioneer brand-new schemes of semiconductor-based all-optical gate devices for breaking-through the technical limits in the up-to-date signal-processing devices and systems, and for use in the future optical networks and computers near the Tera-bit-per-second speed in time. In 2000 for example, he and his colleagues have successfully reached the world-record-first signal-wavelength conversion of optical 168-Gb/s TDM data signals.

In 1996-2002, he was a member of a large-scale, nation-wide research project "Femtosecond Technology," being supported by New Energy and Industrial Technology Development Organization (NEDO, under METI) and led by Drs. Fujio Saito and Teruo Sakurai. In 1996-2005, he was also a member of another nation-wide project "Total Optical Communication," which was supported by TAO/NICT (MIC) and was led by Drs. Akira Hasegawa and Tetsuya Miki.


He has been a member of Optical Society of America (OSA), IEEE Photonics Society, and Japanese Society of Applied Physics (JJAP).
