论文摘要
在这项工作中，我们介绍了从梯度折射率（Grin）培养基的设计，类似于经典力学中最快的下降问题。光线在这种介质中沿着循环散发，其中折射率可以从重力力下的下降速度中确定。它可以用作笑声或波导，并且已经讨论了频率特定的焦点和成像特性。结果表明波导可以看作是光学滤波器。它的频率响应特性随折射率轮廓和设备几何形状而变化。
In this work, we present the design of cycloidal waveguides from a gradient refractive index (GRIN) medium in analogy to the fastest descending problem in classical mechanics. Light rays propagate along cycloids in this medium, of which the refractive index can be determined from relating to the descending speed under gravity force. It can be used as GRIN lenses or waveguides, and the frequency specific focusing and imaging properties have been discussed. The results suggest that the waveguide can be viewed as an optical filter. Its frequency response characteristics change with the refractive index profile and the device geometries.
