Abstract
When an optical signal that is corrupted by laser phase noise is transmitted through a chromatic dispersion limited optical fiber, the phase noise gets converted to intensity fluctuations. In this paper, the performance limitations of coherent optical systems in the presence of the fiber dispersion induced amplitude noise are described. Further, the power penalty incurred due to the presence of this noise with reference to ideal (dispersion-free) transmission is computed from the bit error rate expressions. The two-branch and three-branch ASK phase diversity receiver using squarers have been analyzed for various values of laser linewidth and chromatic dispersion parameter.
