“…[6][7][8][9][10][11] Raman fiber amplifiers may potentially help to achieveamplification in a wide waveband, but the derived fiber amplifier usually has a complex structure and requires high pumping power which strictly limits their commercial applications. [2,4,12] In recent years, it has been discovered that Bi-doped glasses and fibers are potential gain media for broadband amplifiers due to their unique ultra-broadband NIR emission at the E waveband (1360-1460 nm). [13][14][15][16] Since the E band fiber amplifiers based on Bi-doped fibers have been demonstrated, the Bi-activated center for E band emission and the evolution behavior of the Bi-center in glass and glass fiber still remains unknown and the gain coefficients of these gain fibers are relatively low, ranging from ≈0.05 to 0.15 dB m −1 .…”

Bismuth(Bi)‐doped optical fibers are widely used in various aspects such as fiber lasers and amplifiers. Despite extensive research efforts to explore high‐gain Bi‐doped fibers, the pursuit of Bi‐doped fibers with emission over an extremely wide wavelength range remains unfulfilled. Here, the strategy of cluster control via regulating glass structure is proposed. It is applied to construct Bi‐doped photonic glass with ultra‐broadband near‐infrared (NIR) emission and a full width at half maximum (FWHM) of 343 nm. The strategy is further combined with the modified chemical vapor deposition (MCVD) technique with solution doping. The fiber exhibits ultra‐broadband amplified spontaneous emission (ASE) covering the entire fiber communication band (1260–1625 nm). Finally, the fiber exhibits higher optical gain and bandwidth compared with the fiber without cluster control. This device can be utilized to potentially enhance the capacity of telecommunication systems.

Capacity enhancement by utilising the unused spectral bands of the low-loss optical window of standard singlemode fibre (SSMF) is a cost-effective solution for meeting the future demand for data traffic. The development of optical amplifiers that can operate in different spectral bands is expected to play an integral part in the establishment of multi-band networks. In this work, we perform experimental, analytical and numerical modelling of a multi-band transmission system using a hybrid distributed-discrete Raman amplifier enabling signal amplification from 1410-1605 nm. The developed amplifier was tested over 50km of SSMF using 200 Gbit/s channels, where successful transmission was achieved, well above the HD-FEC threshold of 8.5 dB. Further study on the multi-band transmission performance was carried out using a semi-analytical closed-form approximation and split-step Fourier method-based simulations for various related test cases. The analytical and numerical models are also compared with experimental results, showing reasonable agreement in terms of system performance estimation.

Bismuth (Bi)‐doped glass and fiber materials exhibit excellent optical performance and have potential in fields such as fiber communication and tunable lasers. However, the preparation of Bi‐doped glass and fiber with high optical activity is still confronted with huge challenges. This study proposes a germanium oxide hybridization strategy to enhance near‐infrared emission in Bi‐doped glass. In addition, by the systematical optimization of the optical response and processability of the glass system, Bi‐doped glass fibers are successfully constructed. The constructed glass fibers have excellent optical performance, and the enhanced amplified spontaneous emission is realized. They show potentials for applications in broadband fiber amplifiers and tunable lasers.
