Abstract

See full text

An optical switch fabric, including: a first set of horizontal optical waveguides receiving a plurality of wavelengths; a plurality of wavelength-selective drop optical switches associated with the first set of horizontal optical waveguides, wherein the plurality of wavelength-selective drop optical switches are each configured to drop a selected wavelength from a horizontal optical waveguide of the first set of horizontal optical waveguides to an associated vertical optical waveguide of a plurality of vertical optical waveguides; and a plurality of controllable optical switches associated with the plurality of vertical optical waveguides, wherein the plurality of controllable optical switches are each configured to direct a selected wavelength from a vertical optical waveguide of the plurality of vertical optical waveguides to a horizontal optical waveguide of a second set of horizontal optical waveguides, and wherein the second set of horizontal optical waveguides output a plurality of wavelengths.
