The advancement of integrated optics circuits and fiber optics with a view to their application in Navy and other DoD systems is the objective of this ARPA-sponsored NELC program. This report documents progress in a number of areas. Patterns for direct optical waveguides have been fabricated in different materials by electron beam exposure of electron resist. Studies have been performed on the efficiency of planar horn-shaped regions in waveguides as coupling devices. An electron beam microscope has been used to measure the variation in the concentration of the electrically active impurities in laser diodes and other semiconductor structures. An apparatus has been constructed for the measurement of the refractive index of thin films. Low-loss channel waveguides have been produced by focusing an argon ion cw laser with the aid of a microscopic objective on the surface of a piece of highly absorbing glass.
