QD Laser wins IEEE Photonics Society award for commercializing quantum dot lasers
IEEE Photonics Society has awarded the 2014 Aron Kressel Award to QD Laser (Kanagawa, Japan) for pioneering contributions to the development of temperature-insensitive quantum dot (QD) lasers, and their commercialization and mass-production for optical communication systems. The annual award recognizes key contributors to the field for developing critical components that lead to the development of systems enabling major new services or capabilities.
A semiconductor laser using quantum dots in the active layer was first proposed by professors Arakawa and Sakaki of the University of Tokyo in 1982. This laser has unique features such as low threshold current, small temperature sensitivity, and high temperature operation. Based on an R&D collaboration between Fujitsu Laboratories and the University of Tokyo, QD Laser was founded with capital from Fujitsu and Mitsui Ventures. The company successfully developed high density and high uniformity quantum dot technologies, and commercialized quantum dot lasers as light sources for optical fiber communications.
