Abstract
An optical phase modulator having a reduced time drift of an electro-optical response is disclosed. An optical waveguide exhibiting the electro-optic effect includes two serially coupled portions having opposite time drifts of magnitudes of their respective electro-optical responses. As a result, a time drift of an overall electro-optical response of the optical phase modulator is lessened.
