Claim Text:
1. An optical fiber resonator, the resonator comprising: a polarizing single crystal material having a first crystal lattice axis; a first waveguide formed in the polarizing single crystal material; a second waveguide formed in the polarizing single crystal material running parallel to the first waveguide; and an optical fiber sensing coil; wherein the first waveguide comprises a bend that approaches the second waveguide defining a coupling region between the first waveguide and the second waveguide; wherein the first waveguide and second waveguide are polarized to guide light having a polarization state aligned to the first crystal lattice axis; and wherein the second waveguide and the optical fiber sensing coil are coupled into a resonator configuration to form a ring resonator, the second waveguide comprising a first port coupled to a first end of the optical fiber sensing coil, and a second port coupled to a second end of the optical fiber sensing coil.
