20100315697 | OPTICAL WAVELENGTH SWITCH - Various embodiments of an optical switch device are provided. In one embodiment, the optical switch device includes a substrate. A photonic crystal, having a dielectric material, is applied on the substrate. An optical gain layer, having an optical gain material, is disposed above the photonic crystal. The photonic crystal is formed with a second-order distributed feedback structure to emit laser light perpendicular to a plane of the photonic crystal and a first-order distributed feedback structure adapted for reflecting light in the plane of the photonic crystal back into the second-order distributed feedback structure. The first-order distributed feedback structure at least one of fully surrounds the second-order distributed feedback structure and is arranged on two opposing edges of the second-order distributed feedback structure. | 12-16-2010 |

20100046901 | OPTICAL WAVEGUIDE WITH PERIODIC SUB-WAVELENGTH SIZED REGIONS - A guiding element suitable for integrated optics and transmission in the visible wavelength region includes a plurality of sub-wavelength sized regions in two parallel periodic arrangements embedded within a waveguide layer located on a planar substrate. The dielectric constant of each regions may be the same but different from that of the substrate, the waveguide layer, and the cladding. The periodicity, dimensions and shape of the regions of the periodic arrangement are selected to achieve the desired transmission and guiding of the incident radiation spectrum (e.g., parallel to the two periodic arrangements). A transparent layer with a dielectric constant between the dielectric constant of the periodic arrangement and the dielectric constant of the substrate/cladding provides confinement normal to the substrate. | 02-25-2010 |

20100296788 | ELECTRO-OPTICAL MEMORY CELL - An electro-optical memory cell having a non-volatile programmable refractive index and a method of making. The memory cell includes: a waveguiding structure having a transition metal oxide with oxygen vacancies; a plurality of electrodes for applying an electrical field; and an optical detector for detecting a state of the memory cell. The method includes: fabricating a waveguiding structure having a transition metal oxide with oxygen vacancies; positioning a plurality of electrodes for application of an electric field; arranging the transition metal oxide and the electrodes such that when an electric field is applied, the oxygen vacancies migrate in a direction that has a component which is radial relative to a center of the beam path; applying the electric field thereby programming the refractive index to set a state of the memory cell; and detecting the state of the memory cell using an optical detector. | 11-25-2010 |
