BIAXIAL OPTICAL GYROSCOPE

摘要

A biaxial optical gyroscope is provided, which realizes mode separation using the waveguide devices with different material, and the biaxial optical gyroscope includes: a surface Plasmon Polariton Y-type mode splitter(1), a Y waveguide integrated optical device(2), a Y waveguide integrated optical chip(3), a first polarization-maintaining fiber coil(41), a second polarization-maintaining fiber coil(42), directional couplers(51, 52) and detectors(61, 62), wherein the two output ends of the surface Plasmon Polariton Y-type mode splitter(1) are respectively connected to the Y waveguide integrated optical device(2) and the Y waveguide integrated optical chip(3), and the output ends of the Y waveguide integrated optical device(2) and the Y waveguide integrated optical chip(3) are respectively connected to the first polarization-maintaining fiber coil(41) and the second polarization-maintaining fiber coil(42).
