This article explores for an optical binary half subtractor design which is based on the semiconductor optical amplifiers nonlinear characteristics. For that, the difference output operation of data’s has been realized in the one branch with semiconductor optical amplifier realizing XOR operation and for borrow operation the AND logic operation of the data B with complaint of data A is realized in the other semiconductor optical amplifier branch. Accordingly the resulting output waveforms verify the difference and borrow logic operations successfully at data rate of 20Gbps for the return- to-zero pulse pattern. Different numerical simulations depict the good extinction factor ranging from 31 to 18 dB for the data rates of 2.5 to 20 Gbps as against the key design parameters such as pump current and current injection efficiency of the semiconductor optical amplifier.Cite this Article Devendra Kumar Tripathi.
