On to off state transitions can be implemented by changing the coupling factor or the ring length. Wavelength selective switch units are cascaded to form the demultiplexer. Crosstalks below -30dB with 50GHz channel spacing and losses below 1.5dB in the off state are obtained from simulations. Designs using carrier dispersion effect and power consumption estimations are included.13application/pdfeng© 2014 Optical Society of AmericaCrosstalkAdjacent channelsCarrier dispersion effectsChannel spacingsCoupling factorOptical demultiplexersPolarization independentPower consumption estimationWavelength-selective switchesDemultiplexing.research articleElectrónica10.1364/OE.22.01914119156open access191561619168Optics Express22AR/0000015557
