Abstract :
A polarization-independent optical limiter is proposed using two-stage polarization-diversity configured optical parametric amplifiers in gain-saturated condition. Its amplitude level equalizing effect is successfully demonstrated for a 40 Gb/s signal with less than 0.2 dB polarization dependence.
