A method of using an optical device. The method comprises splitting a light beam into a first beam that passes through a first arm of a waveguide, and, into a second beam that passes through a second arm of the waveguide. The method also comprises passing at least one of the first beam or second beam through one or more optical resonators that are optically coupled to at least one of the first or second arms. The method also comprises determining a difference in the light-transmittance of the first beam exiting the first arm and the light-transmittance of the second beam exiting the second arm, and, adjusting the operating wavelength if the difference in transmittance exceeds a predefined value.
