摘要:
提出并数值验证了利用啁啾光纤光栅反馈弧边六角形微腔激光器产生宽带、无时延特征的混沌激光.通过Lang-Kobayashi方程建立啁啾光纤光栅反馈下的弧边六角形微腔激光理论模型,研究弧边六角形微腔激光器偏置电流、反馈强度及啁啾光栅色散系数对混沌激光带宽及反馈时延特征的影响.结果表明,微腔激光器在具有宽带平坦调制响应特性的高偏置电流情况下,通过啁啾光纤光栅色散反馈可以产生无时延特征的宽带混沌,带宽可达14 GHz.
Abstract:
We propose and numerically demonstrate a method of generating wideband chaos laser without time delay signature by using a circular-side hexagonal resonator (CSHR) microlaser with optical feedback from a chirped fiber Bragg grating (CFBG). The theoretical model of the circular-side hexagonal resonator microlaser with chirped fiber Bragg grating feedback is established according to the Lang-Kobayashi equations. The effects of bias current, feedback strength and CFBG dispersion on the bandwidth of the chaos laser and the feedback time delay signature are investigated. The results show that the CFBG-feedback CSHR microlaser can generate a wideband chaos without feedback time-delay signature under the condition of high bias current with a wideband and flat small-signal modulation response and the bandwidth can reach 14 GHz.
