Classification: CPC H  G | IPC G  H

Claim 10:
11. The light-emitting array of claim 1, further comprising:
an intermediate set of multiple nanostructured optical elements positioned at the first surface of the first semiconductor layer, with each nanostructured optical element of the intermediate set being arranged as one or more volumes of dielectric material protruding into the first semiconductor layer or into the corresponding dielectric body of each pixel region and being characterized by an element size relative to the nominal emission vacuum wavelength λ0 and by an element shape;
the intermediate set of multiple nanostructured optical elements being arranged as an array of elements characterized by at least one element spacing relative to the nominal emission vacuum wavelength λ0; and
the element size and shape and the at least one element spacing of the intermediate set resulting in the redirection of at least a portion of light at the nominal emission vacuum wavelength λ0 propagating laterally within the dielectric body or first or second semiconductor layers to exit the array through a first surface of the second semiconductor layer.
