Abstract
Electromagnetic radiation such as, in particular, infrared radiation is detected opto-electronically by means of a superlattice structure forming quantum wells having a single bound state; in the interest of minimizing dark-current, relatively wide barriers are used between quantum wells. Resulting highly sensitive, high-speed detectors can be used in optical communications, for terrain mapping, and for infrared viewing. Furthermore, upon application of a variable electrical potential across the superlattice structure, radiation traversing such structure can be modulated.
