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.

Abstract: An optical device includes an echelle grating and input waveguide arranged such that the echelle grating receives an input signal that exits from a port of the input waveguide. The echelle grating is configured to reflect the input signal such that when the input signal has a plurality of channels, the input signal separates into output signals that each includes a different one of the channels. The device also includes a plurality of output waveguides that each includes a port positioned to receive one of the output signals. The output waveguides include central waveguides. The central waveguides are the three centermost output waveguides when the total number of output waveguides is odd and the two centermost output waveguides when the total number of output waveguides is even. The central waveguides are positioned such that the grating axis passes through the port associated with one of the central waveguides or passes between the ports associated with the central waveguides.
