Abstract : A double-pass bi-directional(DP_BD) pump configuration is proposed for the high efficiency L-band ASE. A L-band ASE of 13.7 dBm output power and 38nm bandwidth of 1566~1604 nm where the ASE power intensity is higher than -16 dBm is obtained by selecting 1480 nm LD and heavily doped erbium fiber with optimized length simultaneously. The DP-BD ASE source has a pump conversion efficiency of 23.4% which is larger than that by double-pass forward (DPF) configuration of 11.8%. Introduction Broadband light source  based on erbium-doped fiber amplifying spontaneous emission (ASE) is a new type of light source with erbium-doped fiber amplifier ( EDFA ). Since the first commercial use of EDFA for all-optical amplification in 1993 has led to the rapid development of optical communication, broadband light sources based on erbium-doped fiber ASE have the same output spectrum as the 1.55" m-band of optical communication, and have The output spectrum is stable, the environment ...
