This tutorial reviews the recent research on fiber-based phase-sensitive amplifiers (PSAs),
and describes how they can be used in transmission systems. We describe the …

Optical parametric amplifiers rely on second-order susceptibility (three-wave mixing) or third-
order susceptibility (four-wave mixing) in a nonlinear process where the energy of incoming …

Recent progress in low-noise optical amplification and signal processing has raised
prospects of practical devices operating below the conventional quantum limit. We review …

In this paper we theoretically derive for the first time a matrix formalism for a coupled dual-

Flat and wide-bandwidth gain spectrum, along with phase-sensitive gain with no need to
generate amplifier input idlers, can be achieved with a coupled dual-core fiber optical …

We investigate the effect of noise loading in a hybrid phase-sensitive amplifier system,

We investigate high fidelity channel replication approaching the idealized notion of channel
cloning with negligible excess noise and distortion. Previously proposed cloning …

Stable four-mode phase-sensitive (4MPS) process was investigated as a means to enhance
two-pump driven parametric multicasting conversion efficiency (CE) and signal to noise ratio …

Optical parametric amplifiers (PAs) utilize highly efficient nonlinear effects in an optical fiber
and they have the ability to operate in phase-sensitive mode. The inclusion of PAs in optical …
