We review our recent progress in the design and operation of 2-micrometer InGaAsSb/AlGaAsSb quantum-well diode lasers. The devices have InGaAsSb quantum-well active regions and AlGaAsSb cladding layers, and all were grown lattice-matched to GaSb subs

Calculation of the optical field distribution in 2 micrometer AlGaAsSb/InGaAsSb/GaSb multiple quantum well (MQW) lasers shows that incorporation of about 100 nm waveguide layers between quantum wells (QW) and cladding layers increases the optical con

We describe room-temperature 2.78-micrometers AlGaAsSb/InGaAsSb multi-quantum well lasers. Pulsed laser operation was observed with threshold currents of 1.1 A, a maximum power output of 95 mW, and a maximum differential quantum efficiency of 9%. Las

Monolithic fanned-out amplifier lasers (acronym: FOAL), are capable of producing high optical power, greater than 1 watt. They operate single wavelength and can be collimated to generate a nearly Gaussian beam useful for applications requiring an ine
