Abstract
In recent paper of all-optical regeneration, they usually used two side-modes injection-locked the Fabry-Perot laser diode and the use of the continuous-wave (CW) probe light suppresses the carrier-induced relaxation oscillation, and high-speed operation is expected. We have proposed and demonstrated all-optical 2R regeneration using a self-seeding injection-locked FP-LD. The original CW probe light was substituted by a self-seeding signal which was produced by a fiber bragg grating packaged in the Fabry-Perot laser diode. We have successfully performed the 10 Gb/s PRBS data 100-km transmission with regeneration at 50 km. From the bit-error rate diagram, the power penalty of 100-km transmission is 3 dB for the self-seeding mechanism and 3.7 dB for the two side-mode injection mechanism.
