This report describes work on optical stripline waveguide modulators and switches. Seventy percent amplitude modulation was achieved with two types of single-stripline modulators. Several sets of optical stripline directional couplers having different waveguide widths and separations were fabricated passive 3 dB coupling lengths as short as 2.0 mm with 97 power transfer were observed. Stripline directional coupler switches were fabricated in which switching as high as 90 was observed. Materials growth and fabrication techniques required in this program are described in Section II of this report. A discussion of the work on the waveguide modulator and the directional coupler switch is contained in Sections III and IV.
