Classification: CPC H  G | IPC G  H

Claim 11:
12. The light-emitting array of claim 1, further comprising:
a back set of multiple nanostructured optical elements positioned within each of the dielectric bodies and being characterized by an element size relative to the nominal emission vacuum wavelength λ0 and by an element shape;
the back 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 back set resulting in the redirection of at least a portion of light at the nominal emission vacuum wavelength λ0 propagating within the dielectric body to exit the array through the second semiconductor layer.
