Abstract. Metasurface silicon-based optical devices are highly integrated and high-performance, meeting the requirements of photonics integrated circuits. We present a design method for metasurface silicon-based gradient index (GRIN) optical lens. With easy calculation, this method supports large-area GRIN elements design. The Luneburg lens and integrated coupler are shown as examples. Such devices show good performances in simulations. The simulations show that the Luneburg lens can focus light from all directions equally well. The optical 1-dB bandwidth of the integrated coupler is about 100 nm. Our method provides a convenient and feasible approach for designing silicon-based GRIN lenses.

硅基集成梯度折射率透镜的设计

摘要。超表面硅基光学器件具有高集成度和高​​性能,满足光子集成电路的要求。我们提出了一种超表面硅基梯度指数(GRIN)光学透镜的设计方法。该方法计算简单,支持大面积GRIN单元设计。以 Luneburg 透镜和集成耦合器为例。这种器件在模拟中表现出良好的性能。模拟表明,Luneburg 透镜可以同样好地聚焦来自各个方向的光。集成耦合器的光学 1-dB 带宽约为 100 nm。我们的方法为设计硅基 GRIN 透镜提供了一种方便可行的方法。
