我们解决了以紧凑的方式从随机定向导波的波导中向空气中提取光的问题。目标是在保留平面处理的同时提高发光二极管的提取效率。对于与入射角无关的提取，优选的晶格设计似乎具有环状傅里叶变换。我们证明了阿基米德格的这个性质。该系统是谐振腔发光二极管的外部部分。数据表明，在保留衬底的平面顶发射器件中，萃取效率可达40%。
We address the issue of extracting light from a waveguide towards air in a compact way for randomly oriented guided waves. The goal is to enhance the extraction efficiency of light-emitting diodes while retaining planar processing. For incidence-angle-independent extraction, preferred lattice designs appear to possess a ring-shaped Fourier transform. We demonstrate this property for an Archimedean lattice. This system is the outer part of a resonant-cavity light-emitting diode. Data suggest that ∼40% extraction efficiency is at hand in a planar top-emitting device retaining its substrate.
