摘要

本文研究了具有克尔非线性特性的单芯光纤中5个qam调制模式信道的同时传输。分析和仿真结果表明，强线性模态耦合的存在会导致非线性损伤的增加。在弱耦合状态下，相互作用的结果具有随机性，也会导致非线性损伤的增加。得到了弱耦合区存在和不存在线性模式耦合时非线性损伤的均方根差的分布直方图。

Interaction of linear mode coupling and nonlinearity in optical space division multiplexed systems

In this paper simultaneous transmission of five QAM-modulated mode channels in a single-core fiber with Kerr nonlinearity properties is investigated. It is shown analytically and by means of simulation that the presence of strong linear mode coupling leads to an increase of nonlinear impairments. In the weak-coupling regime the interaction result has a random nature and can also lead to an increase of nonlinear impairments. The distribution histogram of the difference between rms of nonlinear impairments in the case of presence and in the case of absence of linear mode coupling for the weak-coupling regime is obtained.
