Abstract
The performance degradation of an optical DPSK receiver in the presence of optical channel noise is analyzed. We effectively convert the optical channel noise into an equivalent additive Gaussian noise at the output of the IF filter of the receiver. It is found that the equivalent noise depends on the LO power but is independent of the signal and LO phase noise. The performance degradation is significant if strong channel noise is present.
