The development of all optical super fast arithmetic logic unit (ALU) is one of the most important requirement for construction of super fast all optical processor. All optical half-adder and half-subtractor have performed most of the essential functions of the arithmetic logic unit. Here in this paper the author has proposed a scheme of single module for phase encoded simultaneous operation of half-addition and half- subtraction for the same input bits using four wave mixing (FWM) in semiconductor optical amplifier (SOA). This type of single module for simultaneous operations using phase encoding based on the difference of phase with the reference signal one through FWM in SOA will gives fast response to accomplish the demand of super fast all optical processing. Keywords - ALU, FWM, SOA, half-adder and half-subtractor.
