Analysis and simulation of the effect of spectral width over intensity noise under the impact of higher-order dispersion parameters in the optical communication systems

In this paper, we analyzed the effect of spectral width of different light sources under the individual and combined impact of first- and second-order dispersion parameters both analytically and graphically. This work also covers the amount of intensity noise introduced in an optical system and the power penalty required to compensate this intensity noise at different optical distances. It has been also investigated that reducing the spectral width can minimize the intensity noise and the power penalty under the individual and the combine impact of higher- order dispersion parameters. An experimental set up is also analyzed to support our results.
