DEVICE FOR ONLINE REGENERATION OF A SIGNAL TRANSMITTED BY SOLITONS VIA THE SYNCHRONOUS MODULATION OF SOLITONS USING A NON-LINEAR OPTICAL MIRROR

摘要

P The device of the invention operates the regeneration of online solitons by the synchronous modulation of these solitons using a nonlinear optical mirror (NOLM) as an optical modulator, this NOLM modulator being controlled by a clock signal recovered from the signal soliton by clock recovery means which can be all-optical means or electro-optical means. The NOLM includes an input coupler which can be a 50/50 coupler or an asymmetric coupler. Said input coupler can be a 2x2 or 3x3 coupler. According to a particular embodiment, the regeneration system further comprises a plurality of optical amplifiers and a plurality of filters called guide filters. Application to optical telecommunications over long distances by solitons. /P
