Soliton intensity-dependent polarization rotation

Abstract

We show experimentally and numerically that intensity-dependent polarization rotation does not lead to pulseshape distortions for fundamental solitons because the soliton rotates as a unit. We demonstrate an optical limiter based on nonlinear polarization rotation in a standard, single-mode fiber followed by a polarizer. The output pulse shape from the limiter resembles that of the input, although the pulse width may be different.
