Claim 17:
18. The device of claim 1:
each nanostructured optical element being arranged as one or more volumes of dielectric material protruding into the second semiconductor layer or into a dielectric layer or medium on the second semiconductor layer and being characterized by an element shape and by an element size relative to a nominal emission vacuum wavelength λ0 of the light emitted by the diode structure;
the 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 resulting in the redirection of at least a portion of the light emitted by the continuous diode structure that propagates laterally in the one or more optical modes to exit the device through the second semiconductor layer.
