Abstract :
In this paper, All Optical Half Adder design based on nonlinear characteristics of Semiconductor Optical Amplifier (SOA) is proposed. Sum output of this adder is implemented using SOA-MZI configuration and carry output is implemented using SOA assisted by filtering. To make output of both the gates compatible for logic levels, an EDFA with suitable parameters is included at the output end of AND gate i.e. for carry. Truth table of Half Adder is verified on the basis of O/P power as well as by time domain analysis. Bit error rate and quality factor have been calculated at different bit rates. Satisfactory performance is obtained up to 80Gb/s.
