Various distinguishable characteristics of quantum dot lasers have been achieved recently. In this report, we realized driving-current-control-free 10Gb/s operation of quantum dot lasers in the temperature range 20-90℃ with low-driving-current condition, where modulation current was 25.4-mAp-p and bias current was 23.4-mA. This achievement was owing to both the optimum design, which was based on the newly proposed quantum dot laser operation model, of short cavity structure to relax damping limited maximum modulation bandwidth using quantum dot active region with enhanced optical gain by multiple quantum-dot layers stacking, and application of p-doping to the nearby active region to reduce temperature sensitivity. Further more, we also clarified criteria for high-speed quantum dot lasers. |
