锁模光纤激光器中束缚孤子对的光子数涨落和关联
Photon-number fluctuation and correlation of bound soliton pairs in mode-locked fiber lasers
摘要：
基于复Ginzburg-Landau方程模型，研究了锁模光纤激光器中束缚孤子对的量子光子数涨落和关联。我们发现，依赖于它们的相位差，束缚孤子对的总光子数噪声可以大于或小于单个孤子的总光子数噪声，并且孤子对中的两个孤子相应地具有正或负的光子数相关。首次预言了由于负相关，异相孤子对可以表现出较小的噪声。
英文摘要：
Quantum photon-number fluctuation and correlation of bound soliton pairs in mode-locked fiber lasers are studied based on the complex Ginzburg-Landau equation model. We find that, depending on their phase difference, the total photon-number noise of the bound soliton pair can be larger or smaller than that of a single soliton and the two solitons in the soliton pairs are with positive or negative photon-number correlation, correspondingly. It is predicted for the first time that out-of-phase soliton pairs can exhibit less noises due to negative correlation.
