ABSTRACT:
An electrooptic directional coupler having first and second electrodes for influencing coupling between a segment of a first optical waveguide and a segment of a second optical waveguide, is operated by varying the potential of the first electrode relative to the second electrode during a first interval in accordance with a first function such that the first electrode remains at a first polarity relative to the second electrode, and varying the potential of the first electrode relative to the second electrode during a second interval in accordance with a second function such that the first electrode remains at a second polarity, opposite the first polarity, relative to the second electrode. The integral with respect to time over the first and second intervals of the potential of the first electrode relative to the second electrode is essentially zero.
