    Abstract: A spherical depression lens is formed in a spherical depression in the substrate of the waveguide and a waveguide index lens is formed over the depression lens whereby the combination of the two lenses provides a high resolution waveguide lens for optical waveguides.

    Abstract: A class of multi-layer reflectors using a plurality of low-loss reflective elements composed of absorbing materials in the form of thin films is described wherein the differences between the absorption indices of the materials are used to obtain reflecting boundaries. The class of reflector structures are designed in such a manner that when light is directed onto the structure, a standing wave is generated throughout the structure. Absorbing materials in the nodes of the standing wave do not absorb but absorbing materials in the antinodes provide enhanced absorption.
