    • Light-emitting devices, and related components, systems and methods are disclosed. The light-emitting device can include a multi-layer stack of materials and a support. The multi-layer stack of materials can include a light-generating region and a first layer supported by the light-generating. Thee light-generating region can be between the first layer and the support. The surface of the first layer can be configured so that light generated by the light-generating region can emerge from the light-emitting device via the surface of the first layer. The surface of the first layer can have a dielectric function that varies spatially according to a pattern. The pattern can be formed of holes in the surface of the first layer. The pattern is configured so that light generated by the light-generating region that emerges from the light-emitting device via the surface of the first layer is more collimated than a Lambertian distribution of light.
    • 公开了发光器件及相关部件,系统和方法。 发光装置可以包括多层材料堆叠和支撑。 多层堆叠的材料可以包括发光区域和由光产生支撑的第一层。 发光区域可以在第一层和支撑体之间。 第一层的表面可以被配置为使得由发光区产生的光可以经由第一层的表面从发光器件出射。 第一层的表面可以具有根据图案在空间上变化的介电功能。 图案可以由第一层的表面中的孔形成。 图案被配置为使得通过第一层的表面从发光器件出射的发光区域产生的光比朗伯分布的光更准直。
