Claim 24:
25. A method of making a light converting optical system as recited in claim 14, further comprising providing an optically transmissive surface having a plurality of microscopic bulges separated from each other by smooth and planar portions of the optically transmissive surface, wherein the microstructured broad-area front surface and the thin sheet of opaque reflective material form a light trapping structure configured to provide for multiple transverse light passage through the photoabsorptive film, wherein at least one of the first and second light converting semiconductor materials comprises quantum dots distributed within an optically transmissive material, wherein the light source is monochromatic, wherein the active layer comprises light scattering elements, and wherein the photoabsorptive film comprises a first optically transmissive protective layer disposed in contact with and bonded to a front surface of the active layer and a second optically transmissive protective layer disposed in contact with and bonded to a back surface of the active layer.
