High-speed, room-temperature, quantum well infrared photodetectors (QWIPs) at λ ∼ 4.9 μm have been realized in a strain compensated In0.1Ga0.9As/Al0.4Ga0.6As heterostructure grown on a GaAs substrate. The high-speed properties at room temperature have been optimized by using a specifically designed...
