The device of the regeneration in a line of an optical signal of solitons by a synchronous modulation of the solitons and transmission system comprising such a device

摘要

The invention relates to a regeneration device in a line of an optical signal of solitons by a synchronous modulation of the solitons, said device comprising: - means (c3, clk) for the recovery of a clock signal making it possible to extract the clock timing of the bits of the signal to be regenerated, and - means (mod) of modulation makes it possible to modulate the amplitude and / or the phase of the solitons by the clock signal, characterized in that said modulation means comprises a modulator mach zehnder - (mod) comprising a first (soa1) and a second (soa2) optical amplifiers in a semi - conductor disposed respectively in a first (f5) and a second (f6) arm of the modulator mach zehnder - (mod), and the gain of each of which is modulated on the basis of the recovered clock signal.
