We propose and demonstrate a novel single-longitudinal-mode (SLM) dual-wavelength erbium-doped fiber ring laser incorporating a semiconductor optical amplifier. The SOA biased in its low-gain regime greatly reduces the gain competition of the two wavelengths. The stable SLM operation is guaranteed by a passive triple-ring cavity and a fiber Fabry-Perot filter. The dual-wavelength output with a 40 GHz wavelength spacing is switchable in the range of 1533-1565.4 nm.
我们提出并演示了一种新型的包含半导体光放大器的单纵模(SLM)双波长掺铒光纤环形激光器。工作在低增益状态的半导体光放大器极大地降低了两个波长之间的增益竞争。通过一个无源三环腔和一个光纤法布里-珀罗滤波器确保了稳定的单纵模运转。波长间隔为40 GHz的双波长输出在1533 - 1565.4 nm范围内可切换。
