20110188806 | OPTICAL MULTIPLEXER/DEMULTIPLEXER SYSTEMS CONFIGURED WITH NON-PERIODIC GRATINGS - Embodiments of the present invention are directed to multiplexer/demultiplexer systems. In one aspect, a multiplexer/demultiplexer system includes an input/output waveguide, two or more output/input waveguides, and a planar, non-periodic, sub-wavelength grating. The grating is configured so that when the system is operated as a multiplexer, each wavelength of light output from one of the two or more output/input waveguides is reflected by the grating toward the input/output waveguide. When the system is operated as a demultiplexer, each wavelength of light output from the input/output waveguide is reflected toward one of the two or more output/input waveguides. | 08-04-2011 |

20110095291 | Lateral Growth Semiconductor Method and Devices - A method of growing high quality crystalline films on lattice-mismatched or amorphous layers is presented allowing semiconductor materials that would normally be subject to high stress and cracking to be employed allowing cost reductions and/or performance improvements in devices to be obtained. Catalysis of the growth of these films is based upon utilizing particular combinations of metals, materials, and structures to establish growth of the crystalline film from a predetermined location. The subsequent film growth occurring in one or two dimensions to cover a predetermined area of the amorphous or lattice-mismatched substrate. Accordingly the technique can be used to either cover a large area or provide tiles of crystalline material with or without crystalline film interconnections. | 04-28-2011 |
