Improved optical routing and networking using multi-layer optical circuits

Abstract

An optical circuit is defined. The optical circuit comprises a first substrate forming a first layer of the optical circuit, wherein a first plurality of waveguides are formed on the first layer; and a second substrate forming a second layer of the optical circuit, wherein a second plurality of waveguides are formed on the second layer; wherein the first plurality of waveguides on the first layer and the second plurality of waveguides on the second layer are formed such that at least some of the first plurality of waveguides on the first layer interface with at least some of the second plurality of waveguides on the second layer in a plurality of interaction stages in order to implement a banyan-type network.
