Abstract

We report the fabrication of an upconversion infrared detector, i.e. a quantum well infrared photodetector integrated with a light-emitting diode (named as QWIP-LED). The infrared photo-response spectrum in the upconversion process is in good agreement with the normal photocurrent spectrum of the QWIP, which demonstrates that the long wavelength infrared band at 8μm has been transferred to the near infrared band at 0.8μm by the upconversion process.
