Description
Summary:The performance of a multiwavelength continuous-wave (CW) optical source based on a supercontinuum (SC) has been numerically studied in a 10 Gb s-1 dense wavelength division multiplexed transmission system. The Q factor is calculated as a measure of the system performance. Effects of the bandwidth of the arrayed-waveguide-grating filter, the transmission fibre input power, and the SC spectral flatness on the Q factors are presented. A multichannel equalization filter is used to improve the performance of the multiwavelength CW optical source and good results are obtained. A comparative study of different modulation formats, non-return-to-zero and return-to-zero, is also performed to evaluate their tolerance to linear and nonlinear impairments.
