摘要： A receiver scheme for optical signals in Return-to-zero (RZ) systems comprises a conventional receiver at the input of which is placed an all-optical decision element realized with nonlinear optical elements. This allows obtaining a substantial increase in performance compared with a simple conventional receiver optimized for NRZ signals. In particular, an optical decision is made up advantageously of two non-linear optical loop mirrors (NOLMs) arranged in cascade with an optical amplifier at the input and a pass-band filter at the output. The loops lengths may be different, as may be the splitting ratios of the couplers of the NOLMs.

摘要： A pulsed optical signal regenerator device comprises three optical stages (11,12,13) arranged in cascade between an input (14) to which is applied a signal Si to be regenerated and an output (15) at which is available a regenerated signal Sr. The first stage (11) comprises a first noise suppressor on the zero for noise reduction in the spaces between the input signal pulses. The second stage (12) comprises an inverting converter for transferring to a clock signal (Ck) the information carried by the signal outgoing from the first stage and introducing a logical inversion of the signal for transformation of the pulses affected by noise in spaces affected by noise. The third stage (13) comprises a second noise suppressor on the zero for reduction of the noise in the spaces between the signal pulses output from the second stage. The clock signal can be at a tributary bit rate of the entering signal to obtain a demultiplexer function also.
