Abstract
A technique for changing the cross-sectional profile of a beam of light from, for example, circular or elliptical to thin involves dividing the beam of light into cross-sectional portions, rotating the cross-sectional portions, and then concatenating the rotated cross-sectional portions to form a thin beam. The resulting thin beam has a long dimension that is formed by the concatenation of the cross-sectional portions of the original beam. A device for changing the cross-sectional profile of a beam of light may be fabricated with silicon optical bench technologies or other molding technologies. The device includes facets that divide a beam of light into cross-sectional portions, rotate the cross-sectional portions, and then concatenate the rotated cross-sectional portions to form a thin beam.
