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...
A novel scheme of generating optical Manchester-duobinary signal format using a directly modulated chirp managed laser is proposed and experimentally demonstrated at 10 Gb/s. The generated optical Manchester-duobinary signal has narrow spectrum and has shown to achieve three times more chromatic dispersion tolerance in optical fiber transmission than that of the conventional Manchester signal. The...
