Thesis “Coniugazione di fase <strong>in</strong> un sistema WDM”<br />
Abstract<br />
The ma<strong>in</strong> concern of the thesis is the evaluation of third-order nonl<strong>in</strong>earities (as self-phase<br />
modulation SPM and cross-phase modulation XPM) and their <strong>in</strong>teraction with chromatic<br />
dispersion <strong>in</strong> optical phase conjugation and their impact on system performances.<br />
Overview<br />
Optical phase conjugation is a promis<strong>in</strong>g technique that could be used <strong>in</strong> advanced optical<br />
communication systems to perfectly compensate chromatic dispersion on a wide bandwidth<br />
plac<strong>in</strong>g an optical phase conjugator <strong>in</strong> the middle of the optical l<strong>in</strong>k. In this work we evaluate the<br />
performance of a new technique (Mid Nonl<strong>in</strong>earity Temporal Inversion – MNTI) <strong>in</strong> the mitigation<br />
of nonl<strong>in</strong>earities and chromatic dispersion us<strong>in</strong>g an optical phase conjugator (OPC) <strong>in</strong> a<br />
wavelength division multiplex<strong>in</strong>g (WDM) system. The analysis is due pr<strong>in</strong>cipally us<strong>in</strong>g a<br />
commercial simulator (OptSim) <strong>in</strong> systems limited by SPM (as WDM systems with a channel<br />
spac<strong>in</strong>g of few nanometers) or by XPM (as Dense WDM systems with channel spac<strong>in</strong>g of 25, 50<br />
and 100 GHz) <strong>in</strong> an optical l<strong>in</strong>k of standard s<strong>in</strong>gle mode fiber (SSMF) or of non-zero dispersion<br />
shifted fiber (NZDS-). The results of the simulation show that the OPC can mitigate the SPM on<br />
a wide bandwidth, <strong>in</strong> particular it can compensate perfectly SPM <strong>in</strong> a NZDS- l<strong>in</strong>k. The effects of<br />
SPM, XPM and chromatic dispersion <strong>in</strong> DWDM systems are less mitigated by the OPC, <strong>in</strong><br />
particular XPM drastically reduce the bandwidth of compensation.<br />
The simulation results are then experimentally evaluated on a real system composed by a s<strong>in</strong>gle<br />
channel at 1535 nm and an OPC realized by a semiconductor optical amplifier (SOA) with RZ<br />
data at 10 Gb/s over 600 km of NZDS- fiber.<br />

The ma<strong>in</strong> concern of the thesis is the development of a LabView <strong>in</strong>terface between pc and an<br />
electrical spectrum analyzer (ESA). We also studied classical optical modulation formats as<br />
OOK, DPSK and DQPSK <strong>in</strong> terms of spectral properties and eye diagrams.<br />
