Abstract

A traveling rib-waveguide structure is proposed for single sideband (SSB) modulation. A low- loss parabolic taper is designed to transmit a large infrared laser beam (10 micrometers ) into a narrow channel at an optimal length of 7500 micrometers where the taper opening is 242 micrometers and the rib-channel width is 100 micrometers . The propagation loss of one taper is about 5 to 10%, and this has been confirmed by experimental results.
