Abstract
A PhC all-optical multistep-delay OR-transformation logic gate includes an optical switch unit having a first intermediate-signal output port, a PhC structure unit having a first intermediate-signal input port connected with the first intermediate-signal output port, a reference-light source connected with the reference-light input port of the optical switch unit, a wave absorbing load, a flip-flop unit, and a memory or delayer having an input port connected with a first logic signal and an output port connected with the delay-signal input port of an optical switch unit whose logic-signal input port is connected with a second logic signal; a second intermediate-signal input port of the PhC structure unit is connected with the second intermediate-signal output port of said optical switch unit; a third intermediate-signal output port of the optical switch unit is connected with the wave absorbing load; a clock control-signal is input through the input port of a two-branch waveguide.
