摘要:

首先利用热库理论得到了考虑光纤损耗的孤子传输的量子场方程,然后利用线性近似方法得到了量子孤子在光纤中传输的压缩比,通过数值法研究了初始啁啾对有损光纤中量子孤子压缩性质的影响. 研究结果表明正啁啾可以延缓损耗对孤子压缩的破坏,而负啁啾将加速损耗对孤子压缩的破坏.

关键词: 量子孤子, 啁啾, 损耗, 压缩比

Abstract:

In this paper, the quantum field equation of optical soliton is obtained in the lossy fiber by means of heat reservoir theory. The squeezed ratio of the quantum soliton is obtained with the linear approximation. We study the impacts of the initial chirp on the quantum soliton in lossy fiber with numerical method. The numerical results show that the positive chirp can slower the destruction on the squeezed soliton while the negative chirp quicken the destruction.

Key words: quantum soliton, chirp, lossy, squeezing ratio
