Abstract
An integrated optical communications receiver/alignment system and method. In one embodiment, a method and an apparatus are disclosed in which a semiconductor substrate includes a plurality of outer optical detectors disposed in the substrate. An optically transparent center region such as for example an optical waveguide or an optical fiber is integrated in the semiconductor substrate in a central location relative to the plurality of outer optical detectors. The optically transparent center region is optically coupled to receive an optical communications beam and the plurality of outer optical detectors are employed for alignment and/or tracking purposes.
