非线性耦合器中的Zeno效应与孤子开关

Zeno effect and switching of solitons in nonlinear couplers

F. Kh. Abdullaev, V. V. Konotop, M. Ogren, M. P. Soerensen

摘要:

研究了孤子型脉冲在有耗散的非线性定向耦合器中的Zeno效应。其效果在于耦合器透明度的增加,其中一个臂中的耗散损耗的增加。结果表明,局域耗散可以导致孤子在臂间的切换。伴随开关的功率损耗可以通过使用耗散和有源(特别是奇偶时间对称)段的组合来完全补偿。

英文摘要:

The Zeno effect is investigated for soliton type pulses in a nonlinear directional coupler with dissipation. The effect consists in increase of the coupler transparency with increase of the dissipative losses in one of the arms. It is shown that localized dissipation can lead to switching of solitons between the arms. Power losses accompanying the switching can be fully compensated by using a combination of dissipative and active (in particular, parity-time -symmetric) segments.
