The DPMY is a three-port polarization-maintaining (PM) fiber device specifically designed for fiber-loop-based sensing applications, such as fiber optic gyroscopes and optical current sensors. It integrates a polarizer, a Y-junction coupler, and dual electro-optic phase modulators into a compact structure. Built on Lithium Niobate (LiNbO₃) waveguide technology, the DPMY delivers a high polarization extinction ratio (PER) exceeding 60 dB. This significantly reduces bias drift caused by polarization crosstalk-induced non-reciprocity, ensuring stable and accurate performance. The device is engineered for high reliability and consistent operation across a wide temperature range.
