Pedestal-free 10-GHz pulse compression using comb-like dispersion profiled fibers and its application in 40-Gb/s OTDM systems

A phase shift increasing method (PSIM) is proposed to construct a comb-like dispersion profiled fiber (CDPF) with an optimum-designed dispersion map. Using this CDPF, a 10-GHz, 12-ps pulse generated from an actively mode-locked -doped fiber ring laser (AML-EDFL) is compressed to 2 ps without a pedes...

Description
Summary:A phase shift increasing method (PSIM) is proposed to construct a comb-like dispersion profiled fiber (CDPF) with an optimum-designed dispersion map. Using this CDPF, a 10-GHz, 12-ps pulse generated from an actively mode-locked -doped fiber ring laser (AML-EDFL) is compressed to 2 ps without a pedestal. The compressed optical pulse source is used in a 40-Gb/s 247-Km optical time-division multiplexing (OTDM) system with a transmission power penalty of 0.42 dB. ©
