	Technical report of IEICE. OPE, 113(263) 9-12, Oct 24, 2013We designed and fabricated an integrated 1×4 wavelength selective switch using a silica planar light wave circuit. The channel spacing is 100 GHz and the number of channels is 40. Signal switching experiments show the switch to be error-free and have low power penalty bit-error rate performance.
