The realisation of an InGaAs/InP quantum-well infrared photodetector focal plane array imaging device is reported. The long-wave infrared response is based on the intersubband transition (intraband) in the quantum wells. In addition, a near infrared (interband) response is demonstrated. This work shows the potential of the InGaAs/InP materials system for multi-spectral imaging applications
