Abstract

We report our recent experimental results on mid-infrared InAs/AlGaSb quantum cascade lasers. InAs/AlGaSb superlattice structures that provide large oscillator strength are used as active layers. Observed minimum threshold current density is 0.42kA/cm2 and the maximum operation temperature is 270K.
