Abstract
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.
Claims21
A light-emitting device comprising:
- an interface through which emitted light passes therethrough, the interface having a dielectric function that varies spatially according to a pattern, the pattern arranged to provide light emission that has a substantially isotropic emission pattern and is more collimated than a Lambertian distribution of light.
