Abstract:
The present invention discloses a drop-before-add optical routing and switching system. The drop-before-add optical routing and switching system includes an input waveguide for carrying a multiplexed optical signal comprising optical signals transmitted over a plurality of wavelength channels represented by λ1, λ2, λ3, . . . , λN−1 and λN, where N is a positive integer wherein the input waveguide extending over a first direction. The drop-before-add optical routing and switching system further includes a plurality of second direction waveguides extending over a second direction and intersecting at N intersections with the input waveguide. The drop-before-add optical routing and switching system further includes a plurality of wavelength selective grating switches each disposed on one of the N intersections for selectively transmitting an optical signal of a selected wavelength into an associated one of the second direction waveguide.
