Abstract

We present a two-stage bismuth-doped fiber amplifier (BDFA) that achieves ultra-broadband amplification from 1280 to 1480 nm. The two-stage BDFA is designed to limit the reabsorption of bismuth-doped silica fiber (BDSF) by high-power pumps pulled fluorescence. A peak gain of 37.9 dB was obtained at 1340 nm for a -23 dBm input signal, with >23 dB gain from 1300 to 1470 nm. Furthermore, the gain of 40.0 and 36.1 dB was measured at small signal power for 1340 and 1430 nm, respectively, and the 3 dB saturation output power reaches 16.0 and 14.6 dBm, respectively. In addition, the basic properties and luminescence characteristic of two types of BDSFs fabricated using atomic layer deposition and modified chemical vapor deposition technique worked in the configuration were investigated.

利用两级配置实现 170 nm 带宽的超宽带掺铋光纤放大器。
我们提出了一种两级掺铋光纤放大器(BDFA),可实现 1280 至 1480 nm 的超宽带放大。两级掺铋光纤放大器旨在限制大功率泵浦拉荧光对掺铋硅光纤(BDSF)的重吸收。在输入信号为 -23 dBm 时,1340 nm 波长处的增益峰值为 37.9 dB,1300 至 1470 nm 波长处的增益大于 23 dB。此外,在 1340 和 1430 nm 波长的小信号功率下,分别测得 40.0 和 36.1 dB 的增益,3 dB 饱和输出功率分别达到 16.0 和 14.6 dBm。此外,还研究了利用原子层沉积和改良化学气相沉积技术制作的两种 BDSF 的基本性质和发光特性。

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.
