An RZ DPSK receiver design with significantly improved dispersion tolerance

Donald S. Govan, Nick Doran

Research output: Contribution to journalArticlepeer-review


We show an improved DPSK receiver design which can increase useful dispersion tolerance by up to a factor of two. The increased dispersion tolerance is achieved through optimization of the optical filter at the receiver and the delay of the Mach-Zehnder interferometer. In this paper we fully explain the concept, quantify the gain and provide an explanation for the operation of the receiver.
