Modelling of All Optical Adders with Dispersion Managed Solitons Utilizing Cross gain Modulation in Semiconductor Optical Amplifiers

Agatha H., Arun Jose

Abstract: The need for high bit rate circuit is increasing day by day. Inorder to overcome the bitrate limitation caused by electronic signal processing All Optical Processing (AOP) is required. AOP deals with realising digital circuits using optical elements only. DM solitons have shown great opportunity in long distance high speed optical fiber communication systems because of their superb characteristics which are not achievable in conventional soliton based systems. All optical adders are modelled using suitable combination of AND, OR and XOR gates utilising Cross Gain Modulation (XGM) effect in SOA. In this paper all optical full adder and half adder are modelled using Dispersion Managed (DM) solitons as input pulse and utilising XGM in SOA at 100 Gb/s.
