摘要

介绍了一种基于双向Lyot滤波器和半导体光放大器的多波长光纤激光器。利用强度相关损耗(IDL)机制，在5db带宽范围内获得了94条波长线的平坦多波长光谱。消光比(ER)为9 dB，线间距在0.1 nm处较窄。实验结构中没有使用偏振器，因此IDL机制仅来自SOA。当SOA电流减小时，波长线和多波长平坦度会变差。如果不适当调整偏振控制器(PCs)，则会导致多波长性能下降。

Multiwavelength SOA fiber ring laser based on bidirectional Lyot filter

We have demonstrated multiwavelength fiber laser (MWFL) based on bidirectional Lyot filter and semiconductor optical amplifier (SOA). The intensity dependent loss (IDL) mechanism is utilized to obtain a flat multiwavelength spectrum of 94 wavelength lines within 5 dB bandwidth. The extinction ratio (ER) is 9 dB, while the line spacing is narrow at 0.1 nm. No polarizer is used in the experimental structure, thus the IDL mechanism is only came from SOA. When SOA current is decreased, worse wavelength lines and multiwavelength flatness is achieved. Without proper adjustment of polarization controllers (PCs), the multiwavelength performance is found degraded.
