    摘要: Light-emitting devices, and related components, systems and methods are disclosed. In some embodiments, the devices (e.g., light-emitting diodes) comprise a multi-layer stack of materials including a light generating region and a first layer supported by the light generating region. The surface of the first layer may have a dielectric function that varies spatially according to a pattern. The pattern may be configured so that light that emerges from the device via the surface of the first layer is more collimated than a Lambertian distribution of light.
