Abstract

Some embodiments of the disclosed subject matter provide systems, devices, and methods for tuning resonant wavelengths of an optical resonator. Some embodiments of the disclosed subject matter provide systems, devices, and methods for tuning dispersion properties of photonic crystal waveguides. In some embodiments, methods for tuning a resonant wavelength of an optical resonator are provided, the methods including: providing an optical resonator having a surface; determining an initial resonant wavelength emitted by the optical resonator in response to an electromagnetic radiation input; determining a number of layers of dielectric material based on a difference between the initial resonant wavelength and a target resonant wavelength and a predetermined tuning characteristic; and applying the determined number of layers of dielectric material to the surface of the optical resonator to tune the initial resonant wavelength to a tuned resonant wavelength.
