摘要： An optical pulse generator comprises a source of polarised optical pulses each having a first frequency spectrum, a length of non-polarisation maintaining highly nonlinear fibre (HNLF) connected to the source, and a polarisation rotator connected to the HNLF. An optical pulse output from the source is guided along the HNLF to the polarisation rotator, whereat the polarisation of the pulse is rotated, and wherein the rotated pulse is re-input to the HNLF, guided along the HNLF, and output from the HNLF as a modified optical pulse. The modified optical pulse has a second frequency spectrumthat is broader than the first frequency spectrum due to interaction between the optical pulse with the HNLF, and wherein the modified optical pulse is substantially polarised.

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 S i to be regenerated and an output (15) at which is available a regenerated signal S r . 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 clock signal can be at a tributary bit rate of the entering signal to obtain a demultiplexer function also.
