Abstract (40-Word Limit): A low-loss integrated 1×2 gridless wavelength selective switch (WSS) is reported. The WSS has a fewer waveguide crossings than a conventional device and only one multiplexer is needed. The bandwidth can be controlled from 200 GHz to 4000 GHz. The transmission loss and the crosstalk are less than 5.9 dB and -25.1 dB, respectively.
