Abstract

Modulational instability (MI) is employed in a self-induced ring cavity configuration based on highly nonlinear dispersion-shifted fiber (HNL DSF) and an erbium-doped fiber amplifier to generate a continuous-wave 262-GHz train of 365-fs optical solitons. The laser operates around 1540 nm, with an average output power of 15 mW. MI is achieved at a low threshold as a result of low average cavity dispersion and high fiber nonlinearity. It is shown that, because of the normal dispersion of the HNL DSF, the solitons exist in the average soliton regime.

摘要

调制不稳定性（MI）被应用于基于高非线性色散位移光纤（HNL DSF）和掺铒光纤放大器的自感应环形腔配置中，以产生一列连续波262 GHz、脉宽为365 fs的光孤子。该激光器工作在1540 nm左右，平均输出功率为15 mW。由于平均腔色散低且光纤非线性高，调制不稳定性在低阈值下即可实现。结果表明，由于HNL DSF的正常色散，孤子存在于平均孤子区域。
