| 20150036218 | HYBRID DIFFRACTIVE OPTICAL ELEMENT AND SPECTRAL BEAM COMBINATION GRATING - An integrated optical device that combines a diffractive optical element (DOE) to provide beam combining for coherent beams and a spectral beam combination (SBC) grating for combining beams of differing wavelengths. The device includes a substrate where a periodic pattern for the DOE is formed in the top surface of the substrate in a first direction. A plurality of reflective layers are deposited on the substrate over the periodic pattern so that the layers follow the shape of the pattern. A top dielectric layer is deposited on the plurality of reflective layers so that the top dielectric layer also follows the shape of the periodic pattern. A periodic grating for the SBC is formed into the top dielectric layer in a second direction substantially orthogonal to the first direction. | 02-05-2015 |
