| In addition, the development of high-operating-temperature quantum cascade lasers, which operate without the use of cryogenic materials, may also increase the availability of this approach. Spire's Bandwidth Semiconductor subsidiary has been developing tiny, gallium arsenide based devices called quantum cascade lasers using nanotechnology semiconductor material growth to address this market need. Design of the nano-engineered quantum cascade lasers for the system will be carried out in collaboration with Professor Shun-Lien Chuang of the University of Illinois at Urbana-Champaign, Department of Electrical and Computer Engineering. |
