摘要
为满足人们在混沌应用中对多模激光源的需求,以法布里-珀罗激光器的多模输出作为种子激光,利用光电振荡环的非线性特性产生多模混沌激光。实验结果表明,与传统光电振荡环产生的混沌激光相比,所提方案产生多模混沌激光需要的环路增益降低了3 dB,全谱带宽增加了3.3 GHz,时延特征降低约80%,并且可以产生多模的混沌激光。此外,每个模式均表现出宽带且平坦的频谱特性,模式间相关性随模式间隔的增大显著降低。所提方案为多模混沌激光的产生提供了一种新的方法。
To satisfy the demand for multimode lasers source in chaos applications,the multimode output of a Fabry-Perot laser is used as the seed laser,and the nonlinear characteristics of an optoelectronic oscillation loop is used to generate multimode chaotic lasers in this study.Experimental results indicate that,compared with the conventional optoelectronic oscillation loop for generating chaotic laser,this scheme reduces the required loop gain by 3 dB,increases the full power spectra bandwidth by 3.3 GHz,and decreases the time-delay signature by approximately 80%while generating multimode chaotic lasers.Additionally,each mode exhibits broad and flat power spectra,and the correlation between modes significantly decreases as the mode spacing increases.This paper presents a new method for generating multimode chaos lasers.
