Abstract

The fabrication and characterization of field-induced waveguides (FIGs) as well as guide/antiguide modulators which utilize the FIG concept are presented. Both theoretical and experimental results promise that a relatively strongly confined, low-loss optical waveguide can be achieved. By applying the appropriate bias to the modulator, a guiding or antiguiding situation can be created which corresponds to on- and off-states, respectively. An optical bandwidth from 1 to 1.55 μm, and a propagation loss of 1 dB at 1.3 μm has been achieved
