Manakov系统中的非简并孤子

Nondegenerate solitons in Manakov system

S. Stalin, R. Ramakrishnan, M. Senthilvelan, M. Lakshmanan

摘要:

众所周知,描述波在双模光纤、光折变材料等中传播的Manakov方程可以接纳孤子,孤子允许碰撞时模式之间的能量重新分配,这也导致逻辑计算。本文指出Manakov系统可以容纳更一般类型的非简并基本孤子,它们对应于不同的波数,在碰撞过程中没有能量的重新分布。先前已知的一类孤子,它允许模式之间的能量重新分配原来是一个特殊的情况下,相应的孤立波具有相同的波数在两个模式和相同的速度。我们追踪这种可能性背后的原因,并分析其物理后果。

英文摘要:

It is known that Manakov equation which describes wave propagation in two mode optical fibers, photorefractive materials, etc. can admit solitons which allow energy redistribution between the modes on collision that also leads to logical computing. In this paper, we point out that Manakov system can admit more general type of nondegenerate fundamental solitons corresponding to different wave numbers, which undergo collisions without any energy redistribution. The previously known class of solitons which allows energy redistribution among the modes turns out to be a special case corresponding to solitary waves with identical wave numbers in both the modes and travelling with the same velocity. We trace out the reason behind such a possibility and analyze the physical consequences.
