摘要： A near field light generating element has a polyhedron core and a clad covering the core so as to contact side surfaces of the core. The polyhedron core has a reflection surface that reflects a luminous flux in a direction different from a direction of introduction of the luminous flux via one end side of the near field light generating element. A luminous flux condensing unit condenses the luminous flux reflected by the reflection surface and propagates the condensed luminous flux to the another end side. A near field light generation unit generates near field light from the propagated condensed luminous flux and emits the near field light to the exterior of the near field light generating element via the another end side. The near field light generation unit has an end surface that is exposed to the exterior on the another end side and has at least one side surface that is shielded by a light-shielding film.

摘要： A near-field optical head has a slider with first and second inclined surfaces that confront a magnetic recording medium during recording and reproduction of information. A recording element is formed on one of the first and second inclined surfaces and includes main and auxiliary magnetic poles stacked together with an insulation film interposed therebetween. An optical flux introducing device introduces an optical flux toward the first and second inclined surfaces of the slider, the optical flux having an optical axis inclined relative to the first and second inclined surfaces. A metal film is formed on the other of the first and second inclined surfaces of the slider for propagating the introduced optical flux along an interface between the first and second inclined surfaces to generate near-field light that is irradiated on the surface of the magnetic recording medium to effect recording and reproduction of information.

摘要： 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.
