Abstract

The properties of beam propagation in a periodically-curved optical waveguide beyond the usual perturbative approach are theoretically studied. The existence of unusual and exotic effects, such as dynamic beam splitting, dynamic directional coupling, and reduction of radiation losses are also shown. These unusual and exotic effects are fully similar to the phenomena of dynamic wave function stabilization, ionization quenching and wavepacket dichotomy encountered in multiphoton radiation-matter processes with super-intense and high-frequency laser fields.

周期性弯曲波导中的波传播:量子力学类比
本文从理论上研究了光束在周期性弯曲光波导中的传播特性。此外,还显示了动态波束劈裂、动态定向耦合和减少辐射损失等特殊效应的存在。这些不寻常的奇特效应与在超强和高频激光场的多光子辐射-物质过程中遇到的动态波函数稳定、电离猝灭和波包二分完全相似。
