Abstract

In this paper, we report a study of the features of polarized and unpolarized narrow-band amplified spontaneous emission (ASE) in a low-doped erbium fiber at 976-nm pumping. We demonstrate that ASE noise can be treated as a train of Gaussian-like pulses with random magnitudes, widths, and inter-pulse intervals. ASE noise can also provide a statistical analysis of these three parameters. We also present the data that reveal ASE noise's role in optical spectrum broadening through self-phase modulation of light propagating in a communication fiber. In particular, the data show that the ASE noise derivative defines the broadening's spectral shape.

摘要

在本文中，我们报告了一项关于在976纳米泵浦下低掺杂铒光纤中偏振和非偏振窄带放大自发辐射（ASE）特性的研究。我们证明，ASE噪声可被视为一系列具有随机幅度、宽度和脉冲间隔的类高斯脉冲。ASE噪声还可以对这三个参数进行统计分析。我们还展示了相关数据，这些数据揭示了ASE噪声在通过通信光纤中光的自相位调制实现光谱展宽方面所起的作用。特别是，数据表明ASE噪声导数定义了展宽的光谱形状。
