Two-layered construction of integrated optical circuits and formation of thin-film prisms, lenses, and reflectors

Abstract
We have demonstrated a new form of a two-layered construction of optical circuits. In this method, thin-film optical devices are covered by a single continuous layer of light-guiding film which serves as the interconnections as well as the input and output terminals. We also have demonstrated the construction of thin-film prisms, lenses, and a novel corner reflector in this type of structure.
