Tunneling mediated by conical waves in a 1D lattice
摘要：
一维布拉格诱导带隙系统中三维波包的非线性传播表明，横向效应（自由空间衍射）影响周期性和非线性的相互作用，导致快速和慢速锥形局域波的自发形成。这种激发对应于增强的非线性传输（隧穿）的间隙中，具有独特的功能，不同的两个边缘的带隙，所规定的本地化波的全色散关系。
英文摘要：
The nonlinear propagation of 3D wave-packets in a 1D Bragg-induced band-gap system, shows that tranverse effects (free space diffraction) affect the interplay of periodicity and nonlinearity, leading to the spontaneous formation of fast and slow conical localized waves. Such excitation corresponds to enhanced nonlinear transmission (tunneling) in the gap, with peculiar features which differ on the two edges of the band-gap, as dictated by the full dispersion relationship of the localized waves.
