All optical integrated full adder-subtractor and demultiplexer using SOA-based Mach– Zehnder interferometer
نویسنده
چکیده
By exploiting nonlinear effects in a semiconductor optical amplifier, different functionalities for all-optical digital signal processing are implemented. In particular we demonstrate the logic functions of integrated addition-subtraction and demultiplexing. The all-optical realizations are based on semiconductor optical amplifier (SOA) and Mach–Zehnder interferometer (MZI), which represent one of the most promising solutions due to their compact size, thermal stability and low power operation. Numerical Simulations confirming the described logic devices is done at 40Gbps and for different input combinations.
