Abstract
An apparatus and method for detection of infrared radiation is disclosed. The apparatus includes a detector including a cascaded type II superlattice for detecting infrared radiation. The method includes detecting an infrared radiation signal using a detector that includes n cascading layers comprised of n-1 repeats of a first type II superlattice structure and a tunnel junction, followed by a final (nth) type II superlattice structure, where n is a whole and positive number.

A method comprising:
- detecting an infrared radiation signal using a detector that includes n cascading layers comprised of n-1 repeats of a first type II superlattice structure and a tunnel junction, followed by a final (nth) type II superlattice structure, where n is a whole and positive number.
A method comprising:
- providing an infrared radiation source to emit a source infrared radiation signal;
- receiving the source infrared radiation signal at a gas source and the gas source to generate a transmitted infrared radiation signal;
- and
- detecting the transmitted infrared radiation signal using a radiation detector including a cascaded type II superlattice.
