摘要： Method for determining a perturbation of an optical wave, wherein a first wave which has been subject to a perturbation, is caused to interfere with a second adaptive and continuously adjustable wave, used as a reference wave, in order to obtain a set of interference fringes, the phase of the first wave is reconstructed from this set, and the perturbation is determined from the thereby reconstructed phase. The shape of the wavefront of the second wave is dynamically adjusted so as to obtain a number of interference fringes adapted to the reconstruction of the phase.

摘要： It is propose to use a DI-NOLM comprising an optical loop made of two spools of dispersive fibers with large effective area but of local dispersion of opposite sign and a HLN fiber in between. In this configuration according to the invention, the input optical signal needs to be initially chirped. A nonlinear phase shift is then generated between both counter propagating optical fields inside the HNL as the consequence of the peak power imbalance. Advantageously, it is possible to process RZ or RZ/DSPK with a rather large shape at half-way taking even more than 65% of bit time. This can be achieved without any alteration of the optical regeneration. Moreover, in this configuration by using the method according to the invention, the compensation dispersion is realized inside the DI-NOLM, and so it is not necessary to add a compensating dispersion state at this interferometer.

摘要： A demultiplexer for an optical time-division multiplexed digital signal, which has a signal wavelength λs and is transmitted with a bit rate B, is described. It comprises a Raman active optical medium, a pump source for generating a periodic optical pump signal having a pump wavelength λp and a periodicity of B/n where n is an integer ≧2, and a coupler for coupling the digital signal and the pump signal into the Raman active optical medium. The new demultiplexer exploits the non-linear Raman gain response of the Raman active medium to a high power pump signal and has a narrow time window and a high extinction ratio.
