The impact of large phase noise, typical of cost-effective energy-efficient sources such as VCSELs, on the transmission of a single side-band optical OFDM signal in case of direct detection over uncompensated fiber tracks is investigated thanks to Monte Carlo simulations. Comparison with the results achieved by a semi-analytical approach is reported, in particular when the laser linewidth is comparable to the OFDM subcarrier spacing.

Abstract
The impact of large phase noise, typical of cost-effective energy-efficient sources such as VCSELs, on the transmission of a single side-band optical OFDM signal in case of direct detection over uncompensated fiber tracks is investigated thanks to Monte Carlo simulations. Comparison with the results achieved by a semi-analytical approach is reported, in particular when the laser linewidth is comparable to the OFDM subcarrier spacing.File in questo prodotto:
