Abstract

We experimentally demonstrate full two-dimensional focalization of light beams at visible frequencies by a three-dimensional woodpile photonic crystal. The focalization (the flat lensing) with focal distances of the order of 50-70 μm is experimentally demonstrated. Experimental results are compared with numerical calculations and interpreted by harmonic expansion studies.

摘要

我们通过三维木堆光子晶体实验演示了可见光频率的全二维光束聚焦。实验演示了焦距离约为 50-70 μm 的聚焦（平面透镜）。实验结果与数值计算进行了比较，并通过谐波展开研究进行了解释。
