Quantum-dot microlasers as high-speed light sources for monolithic integration

Short cavity lasers based on deeply etched Bragg-mirrors were fabricated on GaInAs/AlGaAs lasers structures with self-organised GaInAs quantum-dots as active layers. CW operation at room temperature was obtained for lasers with cavity lengths down to 12 /spl mu/m. The microlasers exhibit good modulation properties and can be operated at high temperatures.
