Spectral hole burning induced by reflected amplified spontaneous emission in erbium-doped silica optical fiber pumped at 980 nm

Abstract

We applied an erbrium-doped fiber amplifier characterization method previously reported for 1480-nm pumped amplifiers to a 980-nm amplifier, obtaining absorption and emission coefficients, as well as the dopant concentration in fiber. Gain and fluorescence (amplified spontaneous emission) simulations performed from the obtained features agree well with experimental results. Nevertheless, at certain high-gain circumstances, disagreements appear in the form of spectral hole burning, which can present high magnitudes and whose nature is discussed.

Pump wavelength-dependent spectral-hole burning in EDFAs

Michael J. Yadlowsky

Gain-difference spectra are used to show that 980-nm band pump wavelength changes can significantly effect spectral-hole burning (SHB) in erbium-doped fiber amplifiers (EDFAs). Gain measurements made using a number of different signal and pump wavelengths help to characterize the underlying inhomogeneous spectral properties of EDFAs and a framework for modeling these effects is presented. Despite the difficulty of obtaining the needed subpopulation specific cross section spectra, this model can be used to explain seemingly anomalous changes in the gain spectra of EDFA as a result of changes in signal or pump wavelength.

Gain cross saturation and spectral hole burning in wideband erbium-doped fiber amplifiers

Masao Tachibana, Richard I. Laming, P.R. Morkel +1 more

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.

Room temperature spectral hole-burning in erbium-doped fiber amplifiers

A.K. Srivastava, J.L. Zyskind, James W. Sulhoff +2 more

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.

Observation of Replica Holes in Erbium Doped Silica Fiber

Thiago P. Mayer Alegre, Gustavo S. Wiederhecker, Hugo L. Fragnito

Abstract We observed for the first time to our knowledge the presence of replica holes in the fluorescencespectrum of EDFA. Saturating the Er 3+ transition at a single wavelength we noticed theappearance of spectral holes in the ASE other than the usual one around the saturating laser. Wequalitatively explain the effect and confront the experimental results with the homogeneouslybroadened model. Introduction One of the limiting factors to state-of-the-art DWDM systems is the effect of Spectral Hole Burning (SHB) inErbium Doped Fiber Amplifiers (EDFAs). It has been already observed that the presence of a saturating signal ina given wavelength induces a hole around the signal in the gain and Amplified Spontaneous Emission (ASE)spectra [1],[2]. These holes in EDFAs are typically between 2 and 8 nm width, which is enough to degrade theneighboring channels. The SHB effect is due to the inhomogeneous broadening of the Er 3+ transitions, causedby site-to-site variations of the local electric field in the silica based host, which induces different ions laser linesproperties.This work shows the existence of spectral holes burned at wavelengths far from the saturating laserline, called Spectral Replica Holes (SRHs). The physical background that explains SRHs is based on theinhomogeneously broadened two-level Stark Splitted

Erbium-doped fiber amplifiers: theory of upconversion-pumped operation with a signal wavelength of 850 nm

Bernard Calvas, Paul Urquhart

A model is presented for erbium-doped fiber amplifiers that operate by an upconversion process in which two pump photons at ~800 nm are absorbed and can provide an inverted population and hence the ability to amplify signal photons at ~850 nm. The most important spectroscopic features of the amplifier are identified and used to formulate a theory that predicts how the amplifier gain varies with fiber length and doping density, as well as with launched pump and signal powers. The limitation that amplified spontaneous emission imposes on the gain is investigated, and useful approximate formulas are derived in the limit where amplified spontaneous emission is negligible.

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.>
