Abstract:
1. A method of using an optical device, comprising: splitting a light beam into a first beam that passes through a first waveguide arm of a waveguide structure and into a second beam that passes through a second waveguide arm of said waveguide structure; passing at least one of said first beam or second beam through one or more optical resonators that are optically coupled to at least one of said first waveguide arm or said second waveguide arm; determining a difference in light-transmittance of said first beam exiting said first waveguide arm and light-transmittance of said second beam exiting said second waveguide arm; adjusting said operating wavelength if said difference exceeds a predefined value; and adjusting a resonance frequency of said one or more optical resonators so that an operating wavelength of said light beam is positioned over a sloped portion of a transmittance curve of said at least one first waveguide arm or second waveguide arm optically coupled to said one or more optical resonators.
