摘要：
Phase-inversion between neighboring pulses appearing in carrier-suppressed return-to-Zero pulses is effective in reducing the signal distortion due to chromatic dispersion and nonlinear effects. A generation method of the anti-phase pulses at 40GHz is demonstrated by using semiconductor mode-locked lasers integrated with chirped gratings. Operation principle and pulse characteristics are described. Suppression of pulse distortion due to fiber dispersion is confirmed for generated antiphase pulses. Repeaterless 150-km dispersion-shifted-fiber L-band transmission at 42.7Gbit/s is demonstrated by using the pulse source.
