An all-optical half adder and half subtractor is proposed using Semiconductor Optical Amplifier assisted Michelson Interferometer (SOA-MI) configuration along with two similar Fiber Bragg Grating (FBG) at the end of the interferometric arms to satisfy the truth table of half adder and half subtractor. SOA acts as an amplifier without the need for conversion to electrical signals. The proposed model is designed using all-optical NOR gates with cross-gain modulation (XGM) of SOA at bit rate of 10Gbps. Analysis of performance factors which includes Bit Error Rate (BER), OSNR and Q-factor have been discussed.
