A novel design of optical XOR/OR gate operating at 1 Gbps and implemented by directed logic using integrated semiconductor ring lasers is presented. The proposed design is simple to implement with no optical non-linearities required for switching operation. Modeling of proposed logic gates is performed using the rate equations for counter-propagating electric fields inside the ring lasers.read more
