Abstract
We report a mutually injection-locked erbium-doped fiber amplifier (or laser) and Fabry-Pe/spl acute/rot laser diode link (EDFA-FPLD or EDFL-FPLD) for single longitudinal mode lasing with linewidth of 0.012 nm and sidemode suppression ratio of 42 dB. The 3-dB linewidths of <20 MHz and 350 kHz for the EDFL-FPLD and EDFA-FPLD links, respectively, are reported using interferometric determination. The mode-beating noise can be completely eliminated in the EDFA-FPLD link.
