Abstract
A Y-branch dual electro-optical phase modulator (YBDPM) has a stitched-in zinc oxide diffused waveguide. It is more vacuum stable and has higher resistance to photorefractive damage than currently used Ti-diffused waveguides. The YBDPM is useful in Fiber Optic Gyroscopes (FOG), especially in low frequencies applications.
