Design of photonics half subtractor logics for photonics signal processing

This paper deals with photonics half subtraction design for photonics signal processing by using SOA-MZI configuration. The simulation is used to design the half subtraction operation at 1 Gb/s. The photonics half subtractor logic is implemented by using phase modulation of signals in SOA-MZI. Simulative realization of optical half subtraction is obtained by using three SOA-MZI structure which lead revolution in signal processing for high speed operation. The photonics half subtractor is obtained with good quality of signal. The clear eye diagram and spectrums are observed for each output of subtractor and borrows.
