Quantum-cascade (QC) microlasers with monolithically integrated semiconductor-air Bragg-mirrors based on GaAs were fabricated and investigated. In this paper we report the device properties of QC microlasers with strongly reduced cavity lengths and improved temperature properties. Based on a three-quantum well (3QW) active region design, the cavity length… CONTINUE READING
