“…The power efficiency is lower than standard silica amplifiers, and the NF is higher than 4 dB, typically in the 5-6 dB range. A serious alternative is the Al-silica fibers which allow higher Er3+ concentrations reducing the gain threshold, but high aluminium concentrations can be a problem under radiation (see Ref [6]). …”

“…It has recently been demonstrated [18] that the fiber exhibits an extremely broad gain spectrum nearly 80 nm from 1530 nm to 1610 nm, although it is not necessarily a flat-gain bandwidth. Figure 7 shows the small signal gain spectrum of the tellurite fiber reported in reference [18].…”

Abstract. Broadband and gain-flattened erbium-doped fiber amplifiers are being widely developed to meet the requirements posed by wavelengthdivision-multiplexed transmission systems/networks pursuing the ultimate capacity. One approach is the improvement of erbium-doped fiber itself for broader gain bandwidth or better gain flatness. In addition to the wellknown aluminum-codoped silica fibers and the fluoride glass fibers, rather new materials, such as tellurite glass, or hybrid configurations which utilize two or more erbium-doped fibers with different glass compositions are being examined. Another approach is the use of gain-equalizing optical filters. One of the most promising gain equalizing techniques is the long-period fiber grating. In order to maintain the gain flatness even under variable operational conditions, control schemes of the optical fiber amplifiers are also a critical issue.

Although the success of demonstrating tellurite glass as a waveguide material in many applications, including tellurite fiberization, Nd 3+ -doped tellurite fiber laser, and 1.5 um ultra-broad band Er 3+ -doped optical amplifier, the advance of tellurite is still necessary in the areas of improving the quality of waveguide and understanding the correlations among processing, structure, and desired property, such as nonlinearity, rare-earth spectroscopy, nanocrystalline doping, and microstructured holey fiber.In the paper, we report some initial experimental results on fiberization processing of KNbO 3 -Na 2 O-ZnO-TeO 2 and Er 2 O 3 -WO 3 -TeO 2 systems. The report, in particular, focuses on the thermal characteristics of these glasses.
