Claim 15:
16. The device of claim 1:
each nanostructured optical element being arranged as one or more volumes of dielectric material protruding into the first semiconductor layer or into the corresponding dielectric layer of each composite electrical contact 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.
