Abstract

We report on a linear modulator which automatically operates about its 3-dB point. This device is a 1 x 2 modified directional coupler formed from Ti:LiNbO₃ waveguides operating at the 1.3-μm wavelength. The modulator is theoretically capable of a vol-tage sensitivity of a few microvolts and a linear dynamic range exceeding 85 dB for 1 mW light. Preliminary experimental results for both X-cut and Z-cut devices are presented.
