Paper Abstract

New and novel far-infrared photon detector concepts based on modern epitaxial growth and fabrication techniques are discussed. Simple analyses are carried out to compare the relative merits among three cases based on quantum wells, quantum dots, and free carrier absorptions. Typical results obtained on quantum dot detectors are presented and areas that need improvements are pointed out. Finally some comments are made on the realization of two-dimensional imaging devices.
