Abstract :
We review the capabilities of phase sensitive amplifiers based on periodically poled LiNbO3 (PPLN) waveguides for optical communication. Specifically, we discuss their unique low noise amplification, phase and amplitude regeneration in multi-span transmissions, and multilevel phase coding signal amplification.
