Abstract :
A polarization-independent all-optical switch has been demonstrated based on a nonlinear fiber Sagnac interferometer. The control signal is split and recombined with a time delay, producing two linearly polarized pulses that lie within the temporal switching window of the circuit. Less than 10% variation of the switched output signal was observed as the input polarization was varied.<>
