Abstract
In hybrid multichannel AM/QAM optical fiber transmission systems based on subcarrier-multiplexing (SCM) technique, the performance is affect ed by the joint action of the AM-FM conversion due to the chirping eff ect in semiconductor laser and the chromatic dispersion of the optical fiber, In this letter, analytical expressions of the power spectral d ensity of the nonlinearity distortions due to ''dispersive'' transmiss ion of chirped intensity-modulated signals are calculated, assuming th at the message modulating the semiconductor laser is a Gaussian proces s.
