Shaping soliton properties in optical Mathieu lattices
摘要:
讨论了无衍射马蒂厄光束在光子晶格中诱导的二维孤子的基本性质和稳定性。这样的晶格允许平滑的拓扑变换的径向对称贝塞尔晶格准一维周期的。晶格拓扑结构的变化对基态和偶极模孤子的性质,包括形状、稳定性和横向迁移率等有很大的影响。
英文摘要:
We address basic properties and stability of two-dimensional solitons in photonic lattices induced by the nondiffracting Mathieu beams. Such lattices allow for smooth topological transformation of radially symmetric Bessel lattices into quasi-one-dimensional periodic ones. The transformation of lattice topology drastically affects properties of ground-state and dipole-mode solitons, including their shape, stability and transverse mobility.
