We proposed a novel all-optical XOR logic accompanied with OOK/PSK format conversion by using cascaded semiconductor optical amplifier (SOA) configuration. Within each SOA, the cross phase modulation and nonlinear polarization rotation processes are properly controlled by OOK signals. The eye diagrams and obtained spectra witnessed the effectiveness of operation. A multicast function is also explored in the process of XOR function, and error-free operation (BER <10(-9)) with less than 2.5 dB power penalty is obtained.
