Perspectives of Long-Haul WDM Transmission Systems Based on Phase-Insensitive Fiber-Optic Parametric Amplifiers

International audienceThe deployment of phase-insensitive fiber-optic parametric amplifiers (PI-FOPAs) as inline amplifiers in long-haul WDM transmission systems is discussed, and it is outlined how to design PI-FOPAs to be a valuable upgrade option for this application

Optimum Power Allocation in Parallel Poisson Optical Channel

Abstract-In this paper we investigate the Shannon capacity of single and parallel Poisson channels in different scenarios. At first, by examining the capacity equation of the single Poisson channel, the minimum average power that maximizes the capacity is found. Then, applying the method of Lagrange multipliers on the capacity expression of the parallel Poisson channel, we obtain the optimum power allocation maximizing the parallel Poisson channel capacity

Impact of SBS on polarization-insensitive single-pump optical parametric amplifiers based on a diversity loop scheme

We experimentally and numerically show that the Brillouin back scattering can result in signal distortions in diversity loop-based polarization insensitive single-pump fiber-optical parametric amplifiers, limiting the distortion-free gain to 10-15 dB for typical highly nonlinear fibers
