Gain and Threshold Improvements of 1300 nm Lasers based on InGaAs/InAlGaAs Superlattice Active Regions
Andrey Babichev, Evgeniy Pirogov, Maksim Sobolev +10
A detailed experimental analysis of the impact of active region design on the performance of 1300 nm lasers based on InGaAs/InAlGaAs superlattices is presented. Three different typ…
Lasing of Quantum-Dot Micropillar Lasers under Elevated Temperatures
Andrey Babichev, Ivan Makhov, Natalia Kryzhanovskaya +12
A comprehensive numerical modelling of microcavity parameters for micropillar lasers with optical pumping was presented. The structure with a hybrid dielectric-semiconductor top mi…
Low-Threshold Surface-Emitting Whispering-Gallery Mode Microlasers
Andrey Babichev, Ivan Makhov, Natalia Kryzhanovskaya +11
We report on microlasers based on high-quality micropillars with lasing on whispering-gallery modes. Usage of low-absorbing AlGaAs\Al$\scriptsize…
Observation of long turn-on delay in pulsed quantum cascade lasers
E. D. Cherotchenko, V. V. Dudelev, D. A. Mikhailov +16
We present an experimental study of the turn-on delay in pulsed mid-infrared quantum cascade lasers. We report the unexpectedly long delay time depending on the pumping current, wh…
