Abstract

Provided is a method of tuning a resonance wavelength of a ring resonator. The method of tuning the resonance wavelength of a ring resonator includes preparing a ring resonator which contains a ring waveguide and a dielectric layer covering the ring waveguide, and heating the ring resonator to induce a refractive index phase change of the dielectric layer.
