Patent ID: 7346251

Claim:
A method of manufacturing a device, comprising: (a) manufacturing a substrate having quantum dots; (b) fabricating, from the substrate, a layer of photonic crystal of a predetermined thickness with a lattice of air holes, wherein, (i) the lattice of air holes has a predetermined spacing between said air holes; (ii) the air holes have predetermined sizes; (iii) the lattice of air holes has a first defect with a predetermined size, a second defect with a predetermined size, and a third defect with a predetermined size, wherein the first, second, and third defects are optically coupled to each other; and (iv) the thickness of the layer of photonic crystal, the spacing of the lattice of air holes, the sizes of the air holes, the size of the first defect, the size of the second defect, and the size of the third defect are dimensioned to cause the optically coupled defects to emit substantially white light.
