OPTICAL ARRANGEMENT FOR MANAGING DIVERSITY AND ISOLATION BETWEEN PORTS IN A WAVELENGTH SELECTIVE SWITCH

摘要

An optical device includes an optical port array, an optical arrangement, a dispersion element, a focusing element and a programmable optical phase modulator. The optical port array has at least one optical input port for receiving an optical beam and a plurality of optical output ports. The optical arrangement allows optical coupling between the input port and each of the output ports and prevents optical coupling between any one of the plurality of optical output ports and any other of the plurality of optical output ports. The dispersion element receives the optical beam from the input port after traversing the optical arrangement and spatially separates the optical 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 a selected one of the optical outputs.
