Parametric gain in multiwavelength systems: A new approach to noise enhancement analysis

Abstract:

When one or more signals propagate along the fiber in WDM environment, Kerr nonlinearity interacts with quadratic dispersion yielding parametric phenomena. In particular, the optical carriers can act as pumps and generate spectral regions where small signals experience gain. In long-haul amplified links, signals propagate together with amplified spontaneous emission noise added by in-line erbium-doped fiber amplifiers. Consequently, optical power can be transferred from signal to noise, degrading system performance. A formalism is derived which allows study of the noise enhancement induced by parametric gain in wavelength division multiplexing systems.
