Abstract:
In this thesis, a RoF system using WDM Demultiplexer (DEMUX) is experimentally inquired. A complete phase noise model including optical phase to intensity noise conversion contribution and the phase noise contribution due to the electrical generators is theoretically built up and experimentally demonstrated. Moreover two solutions for converged RoF and WDM-PON access networks are proposed and experimentally investigated. Particularly, a novel multi-band modulation with parallel phase modulations by using a single Mach Zehnder modulator (MZM) is applied in the proposed converged RoF with WDM-PON access networks. The interferences between multi-band modulations with a single optical modulator are theoretically investigated and experimentally demonstrated. Finally, bidirectional RoF based on opto-electronic mixing technique, which is compliant with WDM-PON architecture, is experimentally demonstrated.
