Abstract :
We demonstrate a reconfigurable all-optical logic gate based on predominant nonlinear polarization rotation effect in a single semiconductor optical amplifier. The principle of operation is explained in detail. Five reconfigurable logic functions, including NOT, OR, NOR, AND, and NAND, were realized using 10-Gb/s on-off keying signals with flexible wavelength tenability. The logic operations were achieved by adjusting polarization controllers and the input data power.
