“…SOA based gates have the advantages of requiring a very low switching energy (<1 pJ per pulse [40]), high band width and more compact in size. So it can be integrated easily in chip level [41][42][43][44][45]. Recently high speed operations are successfully demonstrated in many literatures using SOAbased all-optical switch.…”

An all-optical two 2-bit numbers multiplication with the help of Semiconductor Optical Amplifier (SOA)-assisted Sagnac Switch is proposed and described. The paper describes the multiplication using a set of all-optical half-adder and AND gate. Because of the lack of fast, accurate, and large dynamic range analog-to-digital converter, optical implementation of the digital multiplication through analog convolution algorithm yields a slow digital multiplier. By using a set of optical half-adder and optical AND, a new optical fast digital multiplication method is proposed. The new method promises both higher processing speed and accuracy. Numerical simulation result confirming described methods and conclusion are given in this paper.

SUMMARYSymmetric Mach-Zehnder (SMZ) type all-optical switches, namely, the SMZ, polarization-discriminating SMZ (PD-SMZ), and delayed interference signal wavelength converter (DISC), are described in detail. All of these all-optical switches are characterized by pushpull operation and allow ultrafast switching not limited by the relaxation time of high-efficiency nonlinear optical materials that are suitable for low-power operations. They make possible a low-chirp switching window of a quasi-square type that is important in practice. Ultrafast all-optical signal processing with an SMZ, namely, 168 → 10.5 Gbit/s error-free DEMUX (using a hybrid-integrated SMZ, HI-SMZ), zeropenalty optical signal pulse regeneration at 84 and 168 Gbit/s, and error-free all-optical wavelength conversion are reported. In experiments with pulse regeneration and wavelength conversion, the error rate is evaluated after DEMUX to 10.5 Gbit/s by HI-SMZ because the signal light after signal processing has ultrahigh speed.
