Abstract :
An all-optical polarizer, which can repolarize a highspeed data signal without converting the state-of-polarization variations into amplitude jitters, is realized using a mutual injection-locked laser diode. The all-optical polarizer is used to simultaneously realign the state-of-polarizations of two 10-Gb/s polarization-scrambled nonreturn to zero signals without state-of-polarization characterization and feedback control.
