Abstract
Several midwave-infrared (MWIR) lasers have been demonstrated, including 2.8-, 3.1-, 3.2-, 3.4-, 4.1-, and 4.3-μm diodes. The devices utilize multiple-quantum-well (MQW) active regions in which the quantum wells (QW's) consist of InAs-GaInSb broken-gap superlattices (BGSL's). InGaAsSb barrier layers separate the BGSL wells, and InAs-AlSb superlattices are employed as cladding layers. We have observed pulsed laser operation up to 255 K with 3.2-μm devices. Typical pulsed output powers for these devices at 200 K are over 50 mW.
