Abstract
Light-emitting devices, and related components, systems and methods are disclosed.
Claims28
A light-emitting device, comprising:
- a multi-layer stack of materials including a layer of n-doped material, a layer of p-doped material, and a light-generating region;
- and
- a layer of reflective material that is capable of reflecting at least about 50% of light generated by the light-generating region that impinges on the layer of reflective material, wherein:
- a surface of the layer of n-doped material is configured so that light generated by the light-generating region can emerge from the light-emitting device via the surface of the layer of n-doped material;
- a distance between the layer of p-doped material and the layer of reflective material is less than a distance between the layer of n-doped material and the layer of reflective material;
- and
- the layer of n-doped material is supported by the layer of p-doped material.
The light-emitting device of claim 48, wherein the pattern does not extend into the light-generating region.
The light-emitting device of claim 48, wherein the pattern does not extend beyond the layer of n-doped material.
The light-emitting device of claim 48, wherein the pattern extends beyond the layer of n-doped material.
The light-emitting device of claim 48, wherein the pattern is partially formed of a component selected from the group consisting of holes in the surface of the layer of n-doped material, pillars in the layer of n-doped material, continuous veins in the layer of n-doped material, discontinuous veins in the layer of n-doped material and combinations thereof.
The light-emitting device of of claim 48, wherein the pattern of variation is selected from the group consisting of nonperiodic patterns, complex periodic patterns, and patterns having an ideal lattice constant and a detuning parameter greater than zero.
The light-emitting device of claim 48, wherein the pattern is partially formed of holes in the first layer.
The light-emitting device of claim 48, wherein the pattern is configured so that light emitted by the surface of the layer of n-doped material has a spectrum of radiation modes, and the spectrum of radiation modes is substantially the same as a characteristic emission spectrum of the light-generating region.
