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.

摘要： An all-optical contention manager includes at least two inputs and at least two outputs. The outputs are configured to output signals to a Banyan switch. The contention manager detects and resolves routing contentions between incoming optical signals prior to outputting the signals to the Banyan switch. The signals have tags that include routing information. A photonic comparator in the contention manager compares the tags of incoming optical signals in order to detect contention.
