Abstract
High quantum efficiency photodiode device having a pair of photodiodes with light receiving surfaces in parallel spaced relation in a closed cavity. Light is admitted to the cavity through an aperture in such manner that it impinges obliquely upon the light receiving surfaces and is reflected back and forth between the diodes until absorbed. A mirror positioned at the end of the diodes opposite the aperture reflects impinging thereon back to the photodiodes.
