论文摘要
我们通过使用UV-resin吊坠液滴提出并证明并证明非参节性自我加速光束的有效产生和控制。我们表明，由于表面张力和重力之间的相互作用而形成的悬挂液滴的几何形状提供了自然的曲率，从而能够产生非参与性的自动启动光束。通过简单地调节液滴驻留的表面的倾斜角，将传递光束设置为沿着不同的弯曲轨迹传播，弯曲成大角，其非裂开特征优于常规通风梁。这种自动加速光束通过酵母细胞悬浮液中的散射光以及广泛的射线追踪和数值模拟直接追踪。此外，通过实时修改未经吊坠树脂液滴的形状，我们展示了自加速光束的动态轨迹控制。我们的方案和实验方法可以用于基于液滴的其他波，例如微流体喷气机和表面声波。
We propose and demonstrate the effectual generation and control of nonparaxial self-accelerating beams by using UV-resin pendant droplets. We show that the geometrical shape of the hanging droplets formed as a result of the interplay between surface tension and gravity offers a natural curvature enabling the generation of nonparaxial self-accelerating beams. By simply adjusting the tilt angle of the surface where the droplets reside, a passing light beam is set to propagate along different curved trajectories, bending into large angles with non-diffracting features superior to a conventional Airy beam. Such self-accelerating beams are directly traced experimentally through the scattered light in yeast-cell suspensions, along with extensive ray tracing and numerical simulations. Furthermore, by modifying the shape of uncured pendant resin droplets in real time, we showcase the dynamical trajectory control of the self-accelerating beams. Our scheme and experimental method may be adopted for droplet-based shaping of other waves such as microfluidic jets and surface acoustic waves.
