Fumio Koyama received the Ph.D. degree from Tokyo Institute of Technology in 1985. He is the director-general (dean) of the Institute of Innovative Research, Tokyo Institute of Technology. His research interest includes VCSEL photonics, photonic integrated devices, and optical sensing. He has authored or co-authored more than 1,000 journal and conference papers. He received various awards, including IEE Electronics Letters Premium, IEEE/LEOS William Streifer Scientific Achievement Award, the Holonyak Award, and Okawa Award. He is Fellow of OSA, IEEE, IEICE and JSAP.

Koyama realized the first room temperature cw operation of VCSELs in 1988. He has spent much effort on improving and creating new functions for VCSELs for over 30 years. He proposed the creation of a new platform that laterally integrated VCSELs and optical functional devices. This allowed for the creation of a variety of new functions including high-speed modulators, coupled resonators for high-speed direct modulation, high-resolution beam scanners, optical amplifiers, and spatial light switches.
