Abstract:
1. A biaxial optical gyroscope, characterized in that the optical gyroscope including 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 ), a first directional coupler ( 51 ), a second directional coupler ( 52 ), a first detector ( 61 ), and a second detector ( 62 ), wherein, the components are arranged in the following positional relationship: the two output ends of the surface Plasmon Polariton Y-type mode splitter ( 1 ) are connected with the Y waveguide integrated optical device ( 2 ) and the Y waveguide integrated optical chip ( 3 ) respectively, the output ends of the Y waveguide integrated optical device ( 2 ) and the Y waveguide integrated optical chip ( 3 ) are connected with the first polarization-maintaining fiber coil ( 41 ) and the second polarization-maintaining fiber coil ( 42 ) respectively; a first modulation electrode ( 71 ), a second modulation electrode ( 72 ), a first metal wire gap ( 81 ), and a second metal wire gap ( 82 ) are produced on the output end of an upper branch waveguide of the Y waveguide integrated optical chip ( 3 ).
