Abstract
A photodetector, and a method for detecting electromagnetic radiation, is disclosed. The photodetector includes a body which undergoes a detectable, internal physical or chemical change when exposed to electromagnetic radiation, as well as means for detecting this change. The photodetector also includes a substantially periodic surface which increases the efficiency with which incident electromagnetic radiation is coupled onto the photodetector.
