| Research Abstract |
The purpose of our research is to create a novel technique for all-optical forward error detection and correction operating at higher than 40Gbps. As an error detection/correction code for all-optical processing, the cyclic Hamming code was selected. Next, to precisely investigate the operation performance of the all-optical divider circuit consisting of SOA-MZI-based optical XOR circuits, we proposed a novel gain model of a SOA. Then, we simulated the operation performance of the optical XOR circuit based on the SOA-MZI-type all-optical switch by using rate equations, and Q-value of the output signal was evaluated. Moreover, we made experiments of all-optical XOR functions and a divider circuit, we achieved the high signal quality of the XOR and preliminary operation of the divider circuit. Finally, we simulated the operation performance of the divider circuit for error detection consisting of SOA-MZI-type XOR and feedback lines by using rate equations. Error detection is obtained in case that the input signal has errors.
