QD Laser, Fujitsu Laboratories, and the Institute for Nano Quantum Information Electronics, the University of Tokyo today announced the world's first successful operation of a 1.3µm wavelength semiconductor laser at temperatures over 200°C. This was accomplished by utilizing quantum dotsnanometer-sized semiconductor artificial particles. By enabling a broader range of semiconductor laser applications, this technology shows promise for use in extremely high-temperature operating conditions, such as those encountered in oil and gas exploration.
