ABSTRACT:
Alignment difficulties in optical computing arrangements are overcome by integrating the optical components on a single substrate and arranging the elements in a manner that causes them to interact with one another to perform the desired function. The substrate has one or two major surfaces and the elements are grown or fabricated on those surfaces using conventional integrated circuit manufacturing techniques. Most advantageously, the position-sensitive optical devices are manufactured on one side. Reflective planar optical devices are obtained by applying a reflective layer over the fabricated planar optical devices.
