Abstract:
1. An installation comprising an optical regeneration device for a signal carrying an item of information encoded by phase modulation of the signal and comprising a temporal succession of optical pulses, said installation comprising: an optical network inducing a first phase difference between two successive optical pulses having an initial width; means for compensating said phase difference comprising an optical pulse nonlinear phase shift module, the phase shift module comprising a nondispersive and highly nonlinear optical propagation medium and inducing a second phase difference opposite said first phase difference by creating nonlinear interactions between said successive pulses; means for linearly broadening said optical pulses from said initial width to a greater width, situated in the operating chain before the phase shift module and comprising a negatively dispersive and linear optical propagation medium; and means for compensating the broadening of the optical pulses comprising a module for the linear compensation of the broadening undergone by the pulses in the means for linearly broadening the optical pulses, situated in the operating chain after the phase shift module, the linear compensation module comprising a positively dispersive and linear optical propagation medium and narrowing said optical pulses from the greater width to the initial width.
