Abstract
A two stack two color quantum well infrared photodetector (QWIP) for simult aneously detection of LWIR and near infrared (NIR) radiation is demonstrate d. The LWIR sensor is based on a regular GaAs/AlGaAs QWIP, while the NIR se nsor is based on a strained InGaAs/GaAs quantum wells structure. Optical an d electrical measurements of the NIR detector and the inclusive device are presented and discussed. (C) 2001 Elsevier Science B.V. All rights reserved .
