Abstract

Cross-saturation characteristics are investigated in broadband 1.48-microm pumped and 980-nm pumped gainshaped erbium-doped fiber amplifiers. Gain shaping is shown to give a more uniform spectral gain compression on saturation. In addition, a degree of room-temperature spectral gain hole burning is observed for what is to our knowledge the first time.

Spectral Gain Hole-Burning in an Erbium-Doped Fiber Amplifier with GeO2:SiO2 Core

The gain saturation characteristics of erbium-doped fiber amplifiers, which are of importance for applications in optical fiber communications, will depend strongly on the relative importance of homogeneous and inhomogeneous saturation. We have recently reported low temperature spectral hole burning measurements in an erbium-doped fiber with an alumino-silicate core1. From these measurements the homogeneous linewidth was determined to be 11.5 nm. This is consistent with the homogeneous gain saturation observed for alumino-silicate fibers.2 For erbium-doped fibers with GeO2:SiO2 cores, on the other hand, inhomogeneous saturation effects have been reported.3

Spectral gain hole-burning at 1.53 mu m in erbium-doped fiber amplifiers

E. Desurvire, J.L. Zyskind, J.R. Simpson

Spectral gain hole-burning at lambda /sub 0/=1.53 mu m was observed in an erbium-doped fiber amplifier at temperatures between 4.2 and 77 K. The hole width was found to broaden with temperature for T>or=20 K according to a T/sup 1.73/ law. From the data, the room-temperature homogeneous linewidth associated with the 1.531- mu m transition in the /sup 4/I/sub 13/2/-/sup 4/I/sub 15/2/ laser system was determined to be Delta lambda /sub h/=11.5 nm for aluminosilicate fibers.>

Distributed gain and spectral gain-saturation effects in erbium doped fibers

Waldemar Roberto Ruziscka, A.O. Dal Forno, R. Passy +2 more

Distributed gain and spectral gain-saturation effects of erbium-doped fiber amplifier (EDFA) were measured using a coherent reflectrometry technique. We find that the spectral performance can be improved if the gain needs are relaxed. A hole in the spectral dependence of the gain depletion was also observed, which could be related to the Spectral Hole Burning (SHB) phenomenon.

Summary form only given. In this paper we report the first room temperature measurements of spectral hole-burning depths and widths of an Er-doped fiber amplifier (EDFA). The alumino-germano-silicate EDFA was pumped at 1480 nm and had a small signal gain of 25 dB at 1551 nm. Spectral gain measurements were carried out in the range 1535-1570 nm using a lock-in technique and spectral subtraction for accurate determination of SHB properties.
