2x2 wavelength selective switch array

摘要: Methods, systems, and apparatus for optical wavelength selective switching. One 2×2 switch array includes a plurality of input ports configured to receive one or more beams, output beams wherein the form an port pairs; conditioning dispersion elements; polarization modulator having polarizing modulation cells, each cell independently change orientation beam passing through associated with particular channel; polarization-selective beam-routing element route either first second according orientation.
