1. A transverse closed-loop waveguide resonator comprising:

  • an inner cladding having a surface peripherally forming a closed-loop shape for confining light to the surface, the inner cladding having a first diameter thickness and a first index of refraction profile in a cross-sectional portion of the transverse closed-loop resonator; and

    a ringed-core corresponding to the closed-loop shape disposed on the corresponding surface of the inner cladding, the ringed-core having a second thickness of material thinner than the first diameter thickness, and a second index of refraction profile greater than the first index of the inner cladding by an index delta in the cross-sectional portion of the transverse closed-loop resonator such that the ringed-core can guide light within the ringed-core traversely around the closed-loop shape.
