Presently, semiconductor optical amplifiers (SOA) are the key components of all-optical networks. By proposing the SOA-MZI configuration, all optical AND & XOR gate are designed for ultrahigh speed operation. SOA-MZI plays a significant role in the field of ultrafast all optical signals processing, here the non-linear properties of the SOA are properly utilized. In this paper, the performance analysis of SOA-MZI based all optical AND & XOR gate is demonstrated. The performance of these two gates are analysed through their quality factor and bit error rate (BER), recorded with different wavelength and the length of SOA.
