Reconfigurable and simultaneous implementation of all-optical logic gate using four-wave mixing (FWM) in HNLF for NRZ-olSK signal

We demonstrate a reconfigurable all-optical logic gate for NRZ-PolSK signal based on FWM in a highly nonlinear fibe at 10Gb/s. Half-subtracter, XOR, AB, AB or XNOR, AND, NOR logic gates can be implemented simultaneously. Power penalties are less than 3dB.
