“…In 2021, Chen et al reported an Er/Yb/P co-doped fiber amplifier pumped by 1480 nm LDs. The 20 dB gain bandwidth reached 58 nm, and the maximum gain value For the existing extended L-band EDFAs, a Ba-EDFA was demonstrated with a maximum gain of ~42 dB at 1568 nm, exhibiting a border bandwidth of ~63 nm, but the overall gain level was relatively low [7]. In 2023, an amplifier based on 1480 nm diode-pumped Er/Yb/P/Al co-doped fiber was reported with a maximum gain of ~30 dB at 1605 nm.…”

“…Several methods have been reported to achieve the L-band expansion. One of the promising methods is to codope some additional ions such as barium (Ba) [7], cerium (Ce) [8], ytterbium (Yb) and phosphorous (P) [9][10][11][12][13] in erbium-doped fibers (EDFs) to regulate the coordination field and suppress the excited state absorption (ESA) effect of erbium ions in the L-band region. For instance, Chu et al proposed an erbium/phosphorous/aluminum (Er/P/Al) co-doped fiber that expands the gain spectrum of L-band EDFA to 1622 nm [14].…”

Extended L-band erbium-doped fiber amplifiers (EDFAs) have attracted much attention in recent years despite their relatively low gain levels. In this paper, a dual-stage extended L-band EDFA with improved gain level is demonstrated by using an Er/Yb/P co-doped fiber-based double-pass structure assisted by a low noise pre-amplifier. High gain levels of up to 48.79 dB at 1566 nm and 20.05 dB at 1621.4 nm are achieved with saturated output power at 1605 nm of 20.58 dBm under a total pump power of only 400 mW. Bandwidths with the gain of more than 20 and 30 dB are reached up to 66 nm (1555.4–1621.4 nm) and 58.4 nm (1557.5–1615.9 nm), respectively. The noise figure benefited by using the low noise pre-amplifier is 5.40 ± 1.55 dB in the 1565–1610 nm range. The wide gain bandwidth, high gain level and relatively low pump power give it great potential for future high-capacity optical fiber communication systems.

“…For example, the in-band pump technology has been used in phosphate fibers to compensate the low-emission cross-section of Er 3+ ions in L-band, and the extended amplification in L+ band has been achieved. [19][20][21] The above-mentioned fibers have demonstrated good performance in single-stage optical amplification in L-band. However, their physical and chemical properties are quite different than those of silica materials.…”

With the rapid development of 5G networks, the Internet of Things, and new‐generation of AI, there are considerable demands on expanding the capacity of contemporary optical fiber communication systems. One of the most effective avenues involves the extension of the bandwidth of Er‐doped fiber amplifiers, but with limited success. Herein, an Er‐activated hybridized glass fiber are reported, which can help realize broadband telecommunication. The effect of element hybridization on the bandwidth of Er‐activated fiber is clarified and the structure‐optical response relationship is established. A two‐step deposition approach is proposed to overcome the immiscibility barrier of different hybridized elements, and Er‐activated fiber with uniform doping is constructed. The activated fiber presents excellent compatibility with commercial telecommunication systems, providing a small signal gain of >13 dB in the whole L‐band range and a maximum gain of 28 dB. Furthermore, the Er‐activated fiber amplifier device is successfully developed. It exhibits outstanding optical amplification performance with gain >24 dB in the range of 1580–1624 nm, gain fluctuation less than ±0.9 dB, and noise figure <6.5 dB. The results not only provide a new strategy for developing novel active broadband optical fibers, but a valuable solution for new‐generation large‐capacity optical fiber communication systems.
