Recent advances in phase-sensitive amplifiers (PSAs) using periodically poled LiNbO3 are reviewed. Their principles of operation and distinct features are described. Applications in optical communication are studied in terms of the inline operation and amplification of a sophisticated modulation format. Challenges for the future are also discussed.
