An optical microresonator is formed as a microcylinder and a resonant waveguide on the microcylinder and having a plurality of spaced resonant elements such as circumferential ridges for optically coupling light from an optical source waveguide onto the microcylinder. The resonant elements have a spacing, height and angle to impart a desire polarization and bring in the polarization states into degenerancy. A coating could also be formed over the resonant waveguide and operative with the resonant waveguide and of a refractive index to bring any polarization states into degenerancy.
