Abstract

A system for generating a return-to-zero differentially-phase-shift-keyed (RZ-DPSK) optical signal comprising: a driver comprising an N-level digital multilevel transformer (N-level digital transformer) configured to receive a two level digital electrical signal representing 1s and Os and output a N-level electrical signal, wherein N > 2; an FM source configured to receive the N-level electrical signal output by the driver and generate an optical frequency modulated signal (FM/AM source); and an optical spectrum reshaper (OSR) configured to receive the optical frequency modulated signal output by the FM source and generate the desired RZ-DPSK optical signal. A method for generating a retum-to-zero differentially-phase-shift-keyed (RZ-DPSK) optical signal, the method comprising: (1) receiving a two level digital electrical signal representing 1s and Os and outputting a N-level electrical signal, wherein N > 2; (2) receiving the N-level electrical signal output and generating an optical frequency modulated signal; and (3) receiving the optical frequency modulated signal and generating the desired RZ-DPSK optical signal.
