  • Patent number: 8358892
    Abstract: Optical elements (light sources 16 or photodetectors 18) are arranged in a two-dimensional array, and the relative positional relationship between the optical elements and optical waveguides 12 is defined such that optical waveguides 12 extend between the optical elements in the two-dimensional array substantially parallel to substrate 19 for increased parallelism. Micromirrors 15 are disposed in respective optical waveguides 12 to bend light beams through 90 degrees to realize a highly efficient optical coupling between the optical elements and optical waveguides 12. The optical waveguides are stacked in multiple stages, and light beams are lead to the optical waveguides in the multiple stacks through micromirrors 15 across the stacked plane of the optical waveguides, thereby realizing parallel connection between the two-dimensional array of optical elements and a two-dimensional array of optical waveguides.

  • Patent number: 8142054
    Abstract: Provided herein is a light-emitting apparatus capable of achieving both improved durability and higher brightness with an inexpensive and simple construction. A heat resistant glass substrate 51 is mounted in a vacuum chamber 5, and while an anode electrode 8 (and a light emitter 20) is mounted on the glass substrate, the glass substrate 51 is separated from a glass substrate 11. This precisely protects the vacuum chamber 5 from thermal damage due to light emission upon excitation, even when the current density between the cathode electrode 6 and the anode electrode 8 is controlled at a high level to cause the light emitter 20 to emit light at high brightness.

  • Patent number: 7834536
    Abstract: A light-emitting apparatus of the present invention maintains an anode electrode 5 at a higher positive electric potential than a cathode electrode 15, applies an electric field to a cold-cathode electron emission source 16 by controlling a gate voltage applied to the cathode electrode 15 with a gate electrode 10, and emits excitation light from a phosphor 6 irradiated by an electron beam released from the cold-cathode electron emission source 16. The light-emitting apparatus of this invention emits the excitation light not only from the opposite side of the electron beam-irradiated surface of the phosphor 6 through a glass substrate 2, but also from the electron bean-irradiated surface of the phosphor 6 by reflecting the excitation light with a gate reflection surface 12 on the gate electrode 10 and emitting it through an unobstructed area Ro of the glass substrate 2.
