Abstract: Phase-sensitive amplifiers (PSAs) via the optical parametric amplification (OPA) process are capable of near-noiseless amplification, which can improve the performance of optical communications systems. OPA based on periodically poled lithium niobate (PPLN) waveguides is a… read more here.
