ABSTRACT:
Substrate-supported optical device structures such as, e.g. quantum-well infrared detectors/detector arrays are provided with a grating for optical coupling. A binary, reflection grating is designed so that nh is approximately equal to .lambda./4 where n is the refractive index of the grating, h is the thickness of the grating, and .lambda. is a wavelength of interest.
