A novel two color infrared (IR) device that allows fast electrical switching between the short wavelength IR (SWIR) band (0.9-1.6 μm) and the long wavelength IR (LWIR) band (8-12 μm) is presented. The integrated sensor is based on MOCVD grown, lattice matched (to InP substrate) epilayers of InGaAs/InP and consists of two, monolithically integrated sections of heterojunction bipolar transistor (HBT) and quantum well infrared photodetector (QWIP).
