Abstract
An integrated quantum well infrared photodetector for ultra-high speed and frequency sensing in the mid-infrared has been developed. The photodetector is mounted on a microwave connector with either a ´K´ or ´V´ connector. The device was characterised at a temperature of 100 K by optical heterodyne generation of photocurrent in the frequency range DC to 75 GHz. Photoresponse at 75 GHz was approximately 30% that at DC, indicating very fast performance.
