ABSTRACT:
A transverse closed-loop fiber resonator (10) includes an inner cladding (102) having a surface (300) peripherally forming a closed-loop shape for confining light to the surface (300). The inner cladding has a first diameter thickness (104) and a first index of refraction profile in a cross-sectional portion of the transverse closed-loop fiber resonator (10). A ringed-core (120) corresponding to the closed-loop shape is disposed on the corresponding surface of the inner cladding (102). The ringed-core (120) has a second thickness (124) of material thinner than the first diameter thickness (104), 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 fiber resonator such that the ringed-core can guide light within the ringed-core traversely around the closed-loop shape.
