Abstract: We propose a method of suppressing the relative intensity noise caused by polarization-dependent gain that is inherent to Raman polarizers (RPs). This method involves bit-synchronously scrambling the state of polarization of a pulse (bit) before the pulse enters the RP. The proposed solution works for RPs operating in a depleted regime and is compatible with multichannel configurations.

Maggiori informazioni: This work was carried out with support from the Italian Ministry of University and Research (MIUR) in the framework of the \”Scientific Research Project of Relevant National Interest\” (PRIN 2008) entitled \”Nonlinear cross-polarization interactions in photonic devices and systems\” (POLARIZON), the research projects TEC2008-05791 and TEC2011-27314 from the Spanish Ministry of Science and Innovation, and the 2009 Italy-Spain integrated action \”Nonlinear Optical Systems and Devices\” (HI2008-0075). We used VPI Transmission-Maker 8.6 for the numerical estimation of the received BER.Parole chiavi: Multi-channel; Relative intensity noise; State of polarization; Wavelength division multiplexing transmissions, Polarization, Optical instrumentsDOI: 10.1364/OL.37.002073Citazioni: 8dati da “WEB OF SCIENCE” (of Thomson Reuters) aggiornati al: 2022-09-25Riferimenti tratti da Isi Web of Knowledge: (solo abbonati) Link per visualizzare la scheda su IsiWeb: Clicca quiLink per visualizzare la citazioni su IsiWeb: Clicca qui
