Keywords:wavelength selective switch, cross waveguide

A 1×2 wavelength selective switch using wavefront control was fabricated and the switching experiments were performed. Its number of channel is 16 and the each channel spacing is 200 GHz. Since this WSS has no cross waveguide, the variation in loss among channels was improved.
