Paper Abstract

In this paper, we describe low-noise Er-doped optical fiber amplifiers (EDFAs) achieved by exploring novel long period fiber gratings (LPFG) fabrication technique is based on the thermal shock effect of high-frequency CO2 laser pulses at several kHz. By inserting such a LPFG in the Er-doped fiber, the ASE noise of the EDFA has been reduced considerably. Two low-noise EDFAs have been constructed and demonstrated. The ASE noise of the two EDFAs used as a pre- amplifier and an in-line amplifier has been successfully reduced from 4.0dB to approximately 3.5dB and from approximately 4.8dB to approximately 4.3dB with a small- signal gain increase of approximately 7dB for the in-line amplifier, respectively.
