Abstract
Optically interactive nanostructural element. The element includes a semiconductor substrate including at least one radiation guide region extending into the substrate. The geometry of the substrate material surrounding the radiation guide region is selected so that it acts as a quantum confinement region for electrons in the substrate material and the radiation guide region acts as a classical waveguide for radiation so that the element absorbs or emits light of a wavelength corresponding to the selected geometry. In a preferred embodiment, the optically interactive nanostructural element includes an array of the radiation guide regions spatially disposed over a surface.
