A method for fabricating a resonator structure, comprising engineering dispersion of electromagnetic radiation guided along a boundary of an axially symmetric substrate, the engineering comprising micro-structuring a geometry of the boundary, wherein the structure defines a waveguide for electromagnetic radiation.

Method of engineering the dispersion of whispering gallery mode resonators and the resonators with dispersion engineered by the method

An optical device, optical system, and method of generating optical beams having high angular momenta are provided. The optical device includes a whispering gallery mode resonator defining a resonator radius and an elongated waveguide having a length defined between a first end and a second end of the waveguide. The waveguide defines a waveguide radius which increases at least along a portion of the length of the waveguide in a direction from the first end to the second end. The waveguide radius at the first end of the waveguide is smaller than the resonator radius and the resonator is integrally formed with the first end of the waveguide.
