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
