Abstract

In this Letter, we present an all-fiber bismuth (Bi)-doped germanosilicate fiber laser that is continuously tunable within the range of 1425-1475 nm, enabled by a tunable optical filter. A maximum output power of 86.4 mW was achieved at 1450 nm with a slope efficiency of 13.7%. It is, to the best of our knowledge, the first demonstration of an all-fiber tunable continuous-wave (CW) bismuth-doped fiber laser (BDFL) operating in the E + S band. Moreover, a bismuth-doped fiber amplifier (BDFA) was constructed to further scale the laser output power to 159.2 mW with a 21% slope efficiency. Across the 1425-1475 nm range, we achieved >117 mW output power with >50 dB in-band optical signal-to-noise ratio (OSNR).

全光纤E + S波段连续可调谐掺铋锗硅光纤激光器。

在这篇论文中，我们提出了一种全光纤掺铋（Bi）的锗硅酸盐光纤激光器，该激光器在1425-1475 nm范围内连续可调谐，通过可调谐光学滤波器实现。在1450 nm处，最大输出功率为86.4 mW，斜率效率为13.7%。据我们所知，这是在E + S波段工作的全光纤可调谐连续波（CW）掺铋光纤激光器（BDFL）的首次演示。此外，构建了掺铋光纤放大器（BDFA），进一步将激光输出功率扩展到159.2 mW，斜率效率为21%。在1425-1475 nm范围内，我们实现了> 117mw的输出功率和> 50db的带内光信噪比（OSNR）。

期刊介绍： The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
