Abstract

We observed parabolic surface states during the nonlinear propagation of a Weber beams in an SBN crystal. The refractive index is modulated anisotropically using the optical induction technique. These states appear without the need for a pre-inscribed lattice in the material. Their characteristics can be tuned by adjusting the Weber beam’s scale, parabolicity, orientation, and power. We also observed oscillatory discrete surface states during the linear propagation of a probe Gaussian beam within the aperiodic Weber photonic lattice. In both cases, such specific parabolic states are observed as surface states extending across multiple adjacent parabolas, or edge parabolic states localized along the border parabola. Our approach presents the first demonstration of self-induced parabolic surface states in aperiodic systems.

自激抛物表面态

我们观察了韦伯光束在SBN晶体中的非线性传播过程中的抛物表面态。利用光感应技术对折射率进行各向异性调制。这些状态的出现不需要在材料中预先嵌入晶格。它们的特性可以通过调整韦伯光束的尺度、抛物线度、方向和功率来调整。在非周期韦伯光子晶格中，我们还观察到高斯光束在线性传播过程中的振荡离散表面态。在这两种情况下，这种特定的抛物线状态都被观察到作为跨越多个相邻抛物线的表面状态，或沿边界抛物线局部化的边缘抛物线状态。我们的方法首次展示了非周期系统的自诱导抛物表面态。
