Abstract

Abstract Optical feedback control in an optical emitter-detector combination can be improved by fabricating the two devices on a single substrate. The feedback radiation can then travel within a monolithic structure. This arrangement will yield greater uniformity in devices as well as provide for easier mechanical assembly.
