Paper Abstract

An integrated-optic lx2 directional coupler waveguide modulator is described. The device is a modified version of a conventional directional coupler modulator with only one input and two output waveguides. Unlike conventional modulators, this modulator is self-biased. The half-power 3-dB operating point is automatically achieved without the need of a DC bias voltage. In addition, the lx2 modified directional coupler is more efficient than the conventional directional coupler modulator in terms of lower switching voltage and higher linearity.
