All-optical 2R regeneration based on a compact self-seeded Fabry-Perot laser diode with an embedded fiber Bragg grating

Abstract

A cost-effective method, based on the injection-locking technique of a compact self-seeded Fabry-Perot laser diode with a 10-mm-long embedded fiber Bragg grating cavity, is proposed and experimentally compared with the two-mode injection-locked scheme for all-optical 2R regeneration at 10 Gb/s. Placing the presented all-optical 2R regenerator after a 50-km fiber significantly improves the transmission performance of a signal over 50- and 100-km fiber links. The power penalties at BER = 10(-9) are similar to those of the two-mode injection-locked scheme.
