Pulsewidth compression in optical components with polarization mode dispersion using polarization controls

An algorithm capable of finding the input and output states of polarization for pulsewidth narrowing at the output of an optical fiber with polarization mode dispersion (PMD) is analytically presented and numerically solved. It has been demonstrated theoretically and experimentally that the output pulses can he narrower than the input pulses when PMD is compensated by controlling both the input polarization and the receiver polarization states. The cost of this improvement is a reduction of the optical power in the output pulse.
