Abstract

We propose and experimentally demonstrate the generation of various modulation formats using a directly modulated chirp-managed laser (CML), including phase-shaped binary transmission (PSBT), inverse-return-to-zero duobinary (IRZ-duobinary), Manchester-duobinary, return-to-zero differential phase shift keying (RZ-DPSK) and return-to-zero differential quadrature phase-shift-keying (RZ-DQPSK). The CML-based modulation formats improved dispersion tolerance and their corresponding transmitters have the features of compactness, low power consumption and costeffectiveness, which are desired in metro/access networks. System applications of such formats are also studied.
