Quantum well infrared photodetectors (QWIPs) have been developed rapidly and show great potential in infrared detection over a wide wavelength range. Efforts have also been made in using different QWIP structures to achieve multicolor detection. In this report, two specific approaches are presented for voltage tunable multicolor detection. The first approach is to use an electron energy filter to select photoelectrons of specific energies, and the second approach is to use multi-stack QWIP structures.
