Integration of a Detector Array with an Optical Waveguide Structure.

Abstract : Current research under grant involves integration of a detector array with an optical waveguide structure and applications to signal processing. The present report summarizes progress achieved in Part I of this research program (March 15, 1981 - March 14, 1982). The main accomplishments resulting from research performed during this period include a number of accomplishments in the area of laser processing of semiconductors and demonstration of graded index SiO2 waveguides having very low scattering loss. Significant progress was also made with regard to implementation of a log converting array sensor element for charge-coupled device (CCD) image arrays and demonstration of the advantages of edge detection of long wavelength radiation by silicon photodetectors. Results in each of these areas are discussed in the following sections.
