Fiber-optic gyroscope resonant cavity chip based on tunable surface plasmon coupler

The invention discloses a fiber-optic gyroscope resonant cavity chip based on a tunable surface plasmon coupler. The chip comprises a first embedded polarization maintaining optical fiber and a second polarization maintaining optical fiber, which are used to conduct optical signals and stabilize the polarization state of the optical signals; an embedded curved polarization maintaining optical fiber; and a tunable surface plasmon coupler, which is used to adjust the coupling ratio of resonant cavity and realize single-polarization transmission of optical singles in the resonant cavity. The embedded curved polarization maintaining optical fiber and the tunable surface plasmon coupler form a resonant cavity; and the tunable surface plasmon coupler is a surface plasmon waveguide coupler. The first embedded polarization maintaining optical fiber, the second embedded polarization maintaining optical fiber, and the embedded curved polarization maintaining optical fiber are embedded in the peripheral layer of the tunable surface plasmon coupler and butt-jointed with the tunable surface plasmon coupler. The polarization maintaining optical fibers and the tunable surface plasmon coupler are integrated in a same chip, and the whole solid state of chip is realized, so the resonant cavity is more stable compared with conventional resonant cavity of fiber-optic gyroscope, and polarization noise is eliminated.
