ABSTRACT:
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.
