A nano-structure layer is disclosed. The nano-structure layer includes a plurality of nano-photonic structures that are configured in a first configuration such that light incident upon the nanostructured layer below a cut-off angle passes through the nanostructured layer and light incident upon the nanostructured layer above the cut-off angle is reflected back in direction of the incidence. 公开了一种纳米结构层。纳米结构层包括多个配置为第一配置纳米光子材料，使得以低于截止角入射到纳米结构层上的光穿过纳米结构层，并且以高于截止角入射到纳米结构层上的光沿入射方向反射回来。
