Abstract

In this paper, we demonstrate a stable output single-longitudinal-mode (SLM) Erbium-doped fiber laser (EDFL) with eight selectable wavelengths. The EDFL achieves wavelength selection through a 1 × 8 arrayed waveguide grating (AWG) and generates SLM output using the passive triple subring resonator (PTSR) architecture. In the experimental measurements, we separately measured the wavelength, power, and optical signal-to-noise ratio (OSNR) for all eight channels. The experimental results show a wavelength spacing of approximately 0.8 nm, with OSNRs around 60 dB and powers around 2.5 dBm for each channel. The power and OSNR for all eight wavelengths show very little variation. Finally, we measured that the laser outputs are all SLM, and the measured linewidths are all less than 2.5 kHz.

使用 1×8 阵列波导光栅和无源三亚环谐振器的八波长可选单纵模光纤激光器

在本文中，我们展示了一种具有八个可选波长的稳定输出单纵模（SLM）掺铒光纤激光器（EDFL）。EDFL 通过 1 × 8 阵列波导光栅（AWG）实现波长选择，并利用无源三亚环谐振器（PTSR）结构产生 SLM 输出。在实验测量中，我们分别测量了所有八个通道的波长、功率和光信噪比（OSNR）。实验结果表明，每个通道的波长间隔约为 0.8 nm，OSNR 约为 60 dB，功率约为 2.5 dBm。所有八个波长的功率和 OSNR 几乎没有变化。最后，我们测得激光输出均为 SLM，测得的线宽均小于 2.5 kHz。
