A two stack two color quantum well infrared photodetector (QWIP) for simultaneously detection of LWIR and near infrared (NIR) radiation is demonstrated. The LWIR sensor is based on a regular GaAs-AlGaAs QWIP, while the NIR sensor is based on a strained InGaAs-GaAs quantum wells structure. Optical and electrical measurements of the NIR detector and the inclusive device are presented and discussed.
