    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.

    摘要： Devices, such as light-emitting devices (e.g., LEDs), and methods associated with such devices are provided. A light-emitting device may include an interface through which emitted light passes therethrough. The interface having a dielectric function that varies spatially according to a pattern, wherein the pattern is arranged to provide light emission that has a substantially isotropic emission pattern and is more collimated than a Lambertian distribution of light.

    摘要： Devices, such as light-emitting devices (e.g., LEDs), and methods associated with such devices are provided. A light-emitting device designed to emit light may include an interface through which emitted light passes therethrough, wherein the interface has a dielectric function that varies spatially according to a pattern. The pattern may be arranged to provide anisotropic light emission characterized by an emission pattern on a far-field projection plane substantially parallel to the interface, wherein a first total light intensity along a first axis on the projection plane is at least 20% greater than a second total light intensity along a second axis on the projection plane. Alternatively, or additionally, the pattern may be arranged to provide anisotropic light emission characterized by a first total light emission on a first plane that is at least 20% greater than a second total light emission on a second plane, wherein the first and second planes are perpendicular to the interface, and wherein the first and second planes are also perpendicular to each other.
