Abstract :
We describe the first mid-infrared (4 μm) lasers and LEDs utilizing strained InAsSb, multi-stage (or “cascaded”) active regions. An (n)InAs/(p)GaAsSb semimetal layer is incorporated into each stage as an internal electron-hole source. To date, 2-stage LEDs and 2-stage lasers have been demonstrated. Our multi-stage devices were grown by MOCVD
