All-optical in-band OSNR measurement in intensity-modulated direct-detection optical OFDM systems 2013 In-band OSNR measurement for IM/DD O-OFDM systems using high-resolution spectral analysis is experimentally demonstrated. It is shown that noise level can be monitored by direct optical spectrum analysis using no polarization analysis or coherence properties and avoiding the need for data demodulation. info:eu-repo/grantAgreement/ES/MICINN/PTQ-11-04805 info:eu-repo/grantAgreement/ES/MICINN/TEC2010-17869 info:eu-repo/grantAgreement/ES/MICYT/TSI-020100-2011-423 info:eu-repo/grantAgreement/ES/MINECO-FEDER/TEC2012-38119 info:eu-repo/semantics/closedAccess All rights reserved http://www.europeana.eu/rights/rr-f/ info:eu-repo/semantics/conferenceObject info:eu-repo/semantics/publishedVersion Sevillano, Pascual Universidad de Zaragoza (orcid)0000-0002-4094-3826 Moreolo, Michela S.
