Lasing of Quantum-Dot Micropillar Lasers Under Elevated Temperatures
A comprehensive numerical modelling of microcavity parameters for micropillar lasers with optical pumping was presented. The structure with a hybrid dielectric-semiconductor top mirror has a significantly higher calculated quality-factor (∼65000 for 5 μm pillar) due to better vertical mode confinement. The minimum laser threshold (∼370 μW for 5 μm pillar) coincided with a temperature of 130 K, which is close to zero gain to cavity detuning. Lasing up to 220 K was demonstrated with a laser threshold of about 2.2 mW.
