Abstract
An photonic circuit includes a substrate, a plurality of first light waveguides disposed on the substrate, the first light waveguides extending in a first direction, a plurality of second light waveguides disposed on the substrate and extending in a second direction intersecting the first direction, and a plurality of first micro-ring resonators disposed on the substrate. Each of the first light waveguides has an intersection with each of the second light waveguides. Each of the intersections is provided with a first micro-ring resonator of the first micro-ring resonators. Each first micro-ring resonator is configured to route signals of a respective wavelength from one of the light waveguides at the intersection to another light waveguide at the intersection.
