Abstract

Soliton collisions in a WDM transmission system produce power and phase correlations among the interacting channels. The quantum limits of the cross-phase-modulation-induced coupling of solitons were intensively investigated in theory and in experiment, however, only in terms of number-phase correlations. A recent multi-mode analysis of propagating solitons and of the soliton collisions shows intra- and inter-pulse photon-number correlations. This analysis provides new insights into the quantum structure of solitons, into the back-action evading detection of the photon number and into a mechanism of intensity modulation cross-talk in WDM transmission systems in the presence of spectral filters.
