【摘要】：考虑到少模光纤单模工作时具有低非线性以及损耗、色散保持特性,提出基于少模光纤单模工作的量子-经典信号同传方案.使用Optisystem构建了基于少模光纤单模工作的量子-经典信号同传模型,分析了其传输性能,并与现有的基于单模光纤的量子-经典信号同传模型进行了对比.结果表明所提模型可以有效降低现有模型中的非线性效应和信号串扰,将误比特率降低了两个数量级,显著提高了信号的传输质量,可用于量子保密通信大规模网络化.
[Abstract]:Considering the characteristics of low nonlinearity, loss and dispersion retention in single-mode operation of low-mode optical fiber, a quantum classical signal simultaneous interpretation scheme based on single-mode operation of low-mode fiber is proposed. The quantum classical signal simultaneous interpretation model based on the single mode operation of small mode fiber is constructed by using Optisystem. The transmission performance of the model is analyzed and compared with the existing quantum classical signal simultaneous interpretation model based on single mode fiber. The results show that the proposed model can effectively reduce the nonlinear effect and signal crosstalk in the existing models, reduce the bit error rate by two orders of magnitude, improve the quality of signal transmission, and can be used in the large-scale network of quantum secure communication.
