    摘要: Light-emitting devices (e.g., LEDs) and methods associated with such devices are provided. The devices may include a first pattern and a second pattern which are formed at one or more interfaces of the device (e.g., the emission surface). The patterns may be positioned such that light generated by the device passes through the interfaces of the patterns when being emitted. The patterns can be defined by a series of features (e.g., vias, posts) having certain characteristics (e.g., feature size, depth, periodicity, nearest neighbor distance, etc.) which may be controlled to influence properties of the light emitted from the device, including improving extraction and/or collimation of the emitted light.
