Photonic crystal-based permutation switch for optical networks
We present, for the first time, the design of a low-cross talk scalable permutation switch employing photonic crystal ring resonators in an optical network. Through this novel approach, the transition between different states of the 2 × 2 optical switch, as the basic element, is achieved by applying...
