Fiber optic parametric and phase sensitive amplifiers (PSA) are interesting for modern day communication technologies due to their low noise and high gain amplification properties with a potential for all optical signal processing and wide band opera

We propose a new architecture of phase sensitive optical frequency converter based on dual-pump phase sensitive amplification in a highly nonlinear fiber. This frequency converter allows generation of extra tones through nonlinear four-wave mixing be

We develop an analytical model to describe propagation of seven continuous waves [two strong pumps, a degenerate signal and idler, two high-order idlers (HOIs), and two high-order pumps (HOPs)] through a nonlinear fiber. The model is developed consid

Phase sensitive amplifiers (PSA), contrary to usual phase insensitive amplifiers (PIA), are in principle capable to achieve noiseless amplification, i.e. exhibit a quantum-limited noise figure (NF) of 0 db. When implemented using four-wave mixing (FW

Propagation of two pumps and degenerate signal in a dispersion oscillating fiber (DOF) is investigated analytically and numerically. Unlike the single-pump case, the gain side-bands are found to be influenced by the generated high-order pumps.

CW waves in a nonlinear fiber interact through four-wave-mixing processes. Using such interactions, we predict a phase-sensitive frequency conversion functionality in such a system, with two pumps and an idler launched at the fiber input.

International audience; A semi-classical 7-wave model is developed to investigate the noise performances of a degenerate dual-pump phase sensitive amplifier. This approach takes into account the transfer to the signal, through multiple four-wave mixi
