What is claimed: 1. An optical array module, comprising: a thermally conductive and electrically insulative substrate; a plurality of micro-reflectors arranged in an M×N array, M>1 and N>1, and a plurality of light-emitting semiconductor devices arranged on the substrate, wherein a selected number of such plurality of semiconductor devices are disposed on and associated with each such micro-reflector, and wherein light emitted from such selected number of semiconductor devices is substantially collected by the associated micro-reflectors so as to enhance the optical power density from the semiconductor devices; and wherein each micro-reflector comprises a layer of conductive material, the conductive material providing electrical connection for an associated semiconductor device. 2. The optical array module of claim 1, wherein the micro-reflectors are arranged in an array having a center-to-center spacing of about 3 mm or less. 3. The optical array module of claim 1, wherein a side of each micro-reflectors is about 700 square microns. 4. The optical array module of claim 1, wherein each micro-reflector is formed in a truncated pyramidal shape. 5. The optical array module of claim 4, the substrate having a plurality of openings in its surface, the openings being substantially square at the surface, and having sidewalls cut into the substrate that slope to a base, so as to create a truncated pyramidal shape and wherein each such opening provides for formation of a respective one micro-reflector. 6. The optical array module of claim 1, wherein each micro-reflector has a parabolic shape. 7. The optical array module of claim 1, further including an array of micro-lenses, and one or more micro-reflectors is associated with a respective micro-lens, in connection with collection and collimation of light emitted from one or more selected semiconductor devices located within the associated micro-reflector. 8. The optical array module of claim 1, wherein the micro-reflector includes a layer of reflective and conductive material, such reflective material reflecting selected wavelength(s) of light from one or more selected semiconductor devices located within the associated micro-reflector. 9. The optical array module of claim 8, wherein the reflective and conductive material includes silver or aluminum, whereby selected wavelength(s) in the UV spectra are reflected. 10. The optical array module of claim 8, wherein the reflective and conductive material includes gold, whereby selected wavelength(s) in the visible spectra are reflected. 11. The optical array module of claim 1, further comprising a material layered on such substrate, the material having a plurality of openings in its surface, wherein each such opening provides for formation of a respective one micro-reflector. 12. The optical array module of claim 11, wherein the openings enter the substrate. 13. The optical array module of claim 1, wherein the micro-reflector includes a layer of reflective material, such reflective material and the conductive material being the same layer. 14. The optical array module of claim 1 wherein the substrate comprises one or more of ceramic, plastic, diamond, SiC, AlN, BeO, Al2O3.
