Optical arrangement to manage diversity and isolation between ports of wavelength selective switch

摘要

Optical devices include optical port arrays, optical arrays, dispersion elements, focusing elements, and programmable optical phase modulators. The optical port array has at least one optical input port and a plurality of optical output ports for receiving an optical beam. The optical arrangement allows optical coupling between each of the at least one optical input port and each of the optical output ports, and any one of the plurality of optical output ports and any of the plurality of optical output ports. Prevents optical coupling between different ports. The dispersion element receives the light beam from the at least one light input unit after traversing the optical array and spatially separates the light beam into a plurality of wavelength components. The focusing element focuses the plurality of wavelength components. The programmable optical phase modulator receives the focused plurality of wavelength components and steers them to the selected one of the optical outputs.
