Abstract
The ring resonator includes waveguides configured to guide light signals. The waveguides include an input waveguide and one or more loop waveguides. One of the loop waveguides is a primary loop waveguide that is optically coupled with the input waveguide at a wavelength of light. A tuner is configured to tune the wavelength at which the light is optically coupled from the input waveguide into the primary loop waveguide. One or more light detectors are each configured to provide an output indicating an intensity of light guided in one of the one or more loop waveguides. Electronics are configured to tune the tuner in response to the output from the light detector.
