Abstract:
The invention relates to Y-branch waveguide dual optical phase modulators with improved electro-optic (EO) frequency and step responses at frequencies below 1 Hz for use in low-frequency applications such fiber-optic gyroscopes. A Y-branch waveguide structure is formed in an EO substrate, with three or more electrodes used to form a waveguide phase modulator in each of two output waveguide arms. In one embodiment an insulating buffer layer is provided between at least a portion of the electrodes and the substrate for flattening the low-frequency EO response by reducing the modulation efficiency below 1 Hz. In one embodiment each of the waveguide phase modulators includes two ground electrodes extending along both sides of a signal electrode. A top portion of the substrate may be doped to reduce lateral variations of the substrate conductivity in the waveguide and non-waveguide portions thereof between corresponding signal and ground electrodes.
