摘要：
A T-shaped all-optical switch based on nonlinear photonic crystal microring resonator has been analyzed by the finite difference time domain method. Photonic crystal microring resonators are used because they can enhance the nonlinearity due to the localization of light and slow group velocity. By cascading two of these switches we have shown the performance of a NOR gate. The simulations show that in the OFF state the transmission of the proposed NOR gate is only about 2% while in the ON state it is about 81%. (C) 2009 Optical Society of America
