1. A light-emitting device, comprising:
- a multi-layer stack of materials including a layer of n-doped material, a layer of p-doped material, 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,a supporting substrate;
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;
the surface of the layer of n-doped material has a dielectric function that varies spatially according to a pattern; and
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 reflective material is between the layer of p-doped material and the supporting substrate.
