Abstract:

Passive thin film waveguide components investigated under this contract were 1 coupled waveguides, 2 waveguide lenses, 3 taper couplers, 4 waveguides with more or less rectangular cross sections. The coupling between waveguides was investigated in detail, both theoretically and experimentally. Methods for making 3-dB couplers and switches are described. Different experimental methods of making waveguide lenses were attempted however, only two were found to be useful one produces a lens with rectangular contours but thicker in the center and the other produces a round domed lens. Different tapers were investigated. It was found that a well-defined narrow output input angle can be obtained by using a very slow taper. Waveguides with trapezoidal cross sections were produced by sputter-etching of slab type waveguides using photoresist masks. The necessary patterns in these masks were made by exposing the photoresist pattern with a focused beam from a He-Cd laser operating at 4416A. Author
