World's First 10Gbps Quantum Dot Laser
Abstract:
Fujitsu Limited and a research group at the University of Tokyo led by Professor Yasuhiko Arakawa, today announced the joint development of a quantum dot laser that succeeds in minimizing temperature-sensitive output fluctuations, which was not possible with semiconductor lasers in the past. The newly developed quantum dot laser achieves high-speed operation of 10 gigabits per second (Gbps) across a temperature range of 20°C to 70°C without electrical current adjustments, and has minimal output fluctuations caused by changes in temperature. This breakthrough technology will pave the way for compact, low-cost, and low power-consumption optical transmitters targeting optical metro-access systems and high-speed optical LAN for which further development continues.
