1. A monolithic apparatus, comprising:
- means for emitting radiation positioned on the means for supporting; and
means for detecting radiation positioned on the means for supporting adjacent to the means for emitting, wherein the means for emitting is electrically coupled to the means for detecting and the means for detecting receives radiation only from the means for emitting.

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.
