  • Publication number: 20120170604
    Abstract: A planar waveguide laser device forms a waveguide by a plate-like laser medium (1) having birefringence and clad (2a, 2b) attached to at least one of the surfaces of the laser medium (1) perpendicular to its thickness direction, amplifies laser light by a gain produced by excitation light incident on the laser medium (1), and performs laser oscillation. The laser medium (1) is formed of a material having an optic axis on a cross section perpendicular to the light axis, which is the laser travelling direction. The clad (2a, 2b) is formed of a material having a refractive index in a range between refractive indexes of two polarized lights that travel along the light axis in the laser medium (1) and have oscillation surfaces that are orthogonal to each other. The planar waveguide laser device readily oscillates linearly polarized laser light.

  • Patent number: 7952272
    Abstract: In an EL element including a light emitting layer sandwiched between upper and lower electrodes, of light emitted therefrom, light totally reflected at a light emitting layer interface is not taken out, so there is a problem in that light emission efficiency reduces. Therefore, a light scattering layer in which metal particles are dispersed is provided between an electrode and the light emitting layer. According to such a structure, the light from the light emitting layer can be scattered by the metal particles and taken out, thereby improving the light emission efficiency. When plasmon is excited in the metal particles, light confined in the light emitting layer or each layer adjacent thereto can be used, thereby improving light use efficiency.
