20090016395 | TWO-DIMENSIONAL PHOTONIC CRYSTAL SURFACE-EMITTING LASER - Two-dimensional photonic crystal surface-emitting laser comprising a two-dimensional photonic crystal, having media different in refractive index arrayed in a two-dimensional cycle, disposed in the vicinity of an active layer that emits light by the injection of carriers, wherein the two-dimensional photonic crystal consists of square lattices having equal lattice constants in perpendicular directions, and a basic lattice consisting of a square with one medium as a vertex has an asymmetric refractive index distribution with respect to either one of the two diagonals of the basic lattice to thereby emit light in a constant polarizing direction. | 01-15-2009 |
20090135487 | DIFFRACTION GRATING DEVICE AND OPTICAL APPARATUS - A diffraction grating device for splitting or coupling light beams permits the divergence of the light beams to be minimized easily. A first light beam is incident on a diffraction grating from the side thereof facing the inside of the device, and a second light beam is incident on the diffraction grating from the side thereof facing air. The diffraction grating transmits the first light beam by diffraction of the minus first order so that it travels in the reverse direction along the optical path of the second light beam before incidence, and transmits the second light beam by diffraction of the zero order. The second light beam, transmitted by diffraction of the zero order, spreads over a certain width of wavelengths, but does not diverge even after diffraction. | 05-28-2009 |
20130015486 | ORGANIC LIGHT-EMITTING ELEMENTAANM Sekine; KoujirouAACI Ibaraki-shiAACO JPAAGP Sekine; Koujirou Ibaraki-shi JPAANM Yokoyama; MitsuruAACI Takatsuki-shiAACO JPAAGP Yokoyama; Mitsuru Takatsuki-shi JP - An organic light-emitting element including an organic light-emitting layer, a transparent substrate, and a transparent electrode disposed between the organic light-emitting layer and the transparent substrate; and which treats the surface of the transparent substrate on the opposite side from the transparent electrode as a light-extraction surface. The transparent substrate has birefringence, and has a refraction index of a P polarized light that is less than a refraction index of an S polarized light. A polarized light wherein an oscillation direction of an electric field is parallel to a laminated surface of the light-emitting layer is designated S polarized light, and a polarized light that includes a vector of the direction of the progression of the light and in which the oscillation direction of the electric field is included in a plane perpendicular to the laminated surface is designated P polarized light. | 01-17-2013 |
