IEEE Photonics Technology Letters, 2003•ieeexplore.ieee.orgWe present a novel configuration for carrier-suppressed return-to-zero (CSRZ) signal
generation, which only requires a single-stage Mach-Zehnder modulator in conjunction with
an electrical mixer. An electrical band-limiting filter is also introduced to further reduce the
spectral width of the generated CSRZ signal. The proposed scheme is potentially cost-
effective, and simulation results show that the electrically band-limited CSRZ signal exhibits
larger dispersion tolerance than a conventional CSRZ signal without any degradation in its …
