“…It is apparent that with the increase of the aluminum level, the wavelength of the absorption peak shifts to a shorter wavelength and the absorption at 1480nm becomes higher relative to the absorption peak. To examine the effect of aluminum concentration on EDF's spectral gain shape, the gain spectra of these three fibers were determined using equation (1). The spectral bandwidth used was 36nm from 1529nm to 1565nm and the flatness was optimized by selecting proper average inversion level to set zero tilt between minimum gains near 1538nm and 1565nm.…”

Erbium doped fiber amplifiers have been widely deployed for signal amplification in optical transmission systems. High performance amplifiers require erbium doped fiber with high power conversion efficiency and consistent flat gain spectrum. In addition, all impairments associated with EDF must be under good control. This paper reviews the current status and recent progress on erbium doped fibers, illustrates C and L-band spectral characteristics resulting from different doping compositions, presents some approaches for efficient high power amplifiers, and discusses some EDF nonlinear effects with examples.

“…Erbium-doped fiber amplifiers (EDFA) continue to be widely used in long-haul/metro transport systems and CATV applications because they offer cost effective solutions for optical amplification (1) . High performance EDFAs require precise control of doping composition of EDFs to maintain consistent and flat EDFA spectral gain shape.…”

“…In principle, these devices have ideal characteristics compared with conventional fiber-based solutions, but manufacturing difficulties, product performance and value, and market conditions have hindered the implementation of these devices in current commercial telecommunications systems. Many of the anticipated advantages of these devices over conventional fiber-based devices have been negated by engineering solutions, at least for current 10 Gb/s speed systems [e.g., 11]. The deployment of faster speed systems that run at higher peak powers may awaken commercial interest in these devices.…”

This paper provides an overview and technology update of a dispersion management component made from chirped fiber Bragg gratings. The history and technology of fiber Bragg gratings (FBGs) have been extensively covered in several excellent review articles, [1-6] book chapters, [7] and books. [8,9] We give a brief overview of fiber Bragg grating technology in this section and then focus on the details concerned with construction and performance of dispersion management devices in optical communications systems with a single broadband long-length grating used in reflection. Sampled chirped grating are sometimes referred to as broadband devices, but they actually have a narrow bandwidth of operation that is periodically repeated across a given spectral range. Although these periodic devices have shown promise as dispersion management devices in communications systems, they will not be discussed in this paper.

Characteristics of gain spectral variation of EDFs and its dependence on aluminum doping level and fiber mode design are quantitatively studied. Based on experimental data and manufactured fibers with different aluminum levels, the correlation between aluminum concentration and both absorption spectrum and gain flatness is revealed. Gain spectral variation for over a million meters of EDFs manufactured in last several years is presented. The result shows that peakto-peak spectral shape variation for all these fibers are within 0.8% in a 36nm C-band window.
