摘要
利用掺铒光纤环形激光器(EDFRL),基于光纤的非线性克尔效应,实验实现了多波长混沌激光输出。实验研究了EDFRL在时序上通过倍周期进入混沌的路径,并进行了理论分析,理论研究与实验结果一致。实验结果表明,随着抽运功率的增加,其光谱的输出呈现多波长,激光器最多可输出5个不同波长的混沌激光。采用光纤光栅进行滤波后,各个波长的输出均呈现混沌状态。
Abstract
Based on the nonlinear Kerr effect, the multi-wavelength chaos is generated in erbium-doped fiber ring laser (EDFRL) experimentally. Period-doubling route to chaos is observed in time series. Numerical simulation is also carried out, and the numerical results agree with the experimental results well. The experimental results show that the optical spectra of multi-wavelength chaotic fiber laser can output five different wavelengths at most with the pump power increasing, and the output of each wavelength is chaotic after a tunable fiber Bragg grating filter.
