摘要： According to a method for manufacturing a metal grating structure of the present invention, in filling a concave portion formed in a silicon substrate (30), for instance, a slit groove (SD) with metal by an electroforming method, an insulating layer (34) is formed in advance on an inner surface of the slit groove (SD) as an example of the concave portion by a thermal oxidation method. Accordingly, the metal grating structure manufacturing method is advantageous in finely forming metal parts of the grating structure. A metal grating structure of the present invention is manufactured by the above manufacturing method, and an X-ray imaging device of the present invention is incorporated with the metal grating structure.

摘要： A two-dimensional photonic crystal plane emission laser of the invention includes a two-dimensional photonic crystal which has a two-dimensional photonic crystal area and a light reflecting area, and which selects a wavelength of light to be generated in an active layer. The light reflecting area is formed in such a manner that when light leaking from the two-dimensional photonic crystal area and reflected on a reflecting surface of the light reflecting area is returned to the two-dimensional photonic crystal area, the reflection light is combined with a standing wave residing in a propagating direction of the reflection light without disturbing its resonant state.

摘要： On a waveguide 34 formed on a substrate 33, a plurality of comblike shaped electrodes 37, 38 that generate surface acoustic waves 37a, 38a from different directions are provided. And a periodic refractive indices portion 40 is formed, where the refractive indices are periodically distributed in accordance with the wavelengths of the surface acoustic waves 37a, 38a generated by applying a voltage to the comblike shaped electrodes 37, 38. And by changing a frequency of the applying voltage for sequentially changing the wavelengths of the surface acoustic waves 37a, 38a, the exiting direction of the light exiting from the periodic refractive indices portion 40 is scanned. This makes it possible to provide an optical functional device and an optical scanning apparatus that perform light scanning less costly but at a high speed, and that can secure a wide scanning angle.

摘要： An optical module has a substrate, a waveguide, formed on the substrate, for guiding light, and a photonic crystal portion that has media having different refractive indices arranged in a periodic pattern and that is disposed in a channel of the waveguide on the substrate. Here, the photonic crystal and the substrate are integrally formed. The formation comprises the steps of forming an aluminum film on the top of a conductive substrate, forming a protective film on the aluminum film, removing the protective film from a predetermined area to form a window over the predetermined area, anodizing the aluminum film exposed through the window to form photonic crystals, removing the protective film, cladding the bottom of the substrate and forming a core layer over the cladded bottom.

摘要： 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.

摘要： A light-condensing head has a light source unit, a light-condensing element that condenses the light emitted from the light source unit, and an electrically conductive scatterer that, when irradiated with light, produces localized plasmon at the light condensation position of the light from the light-condensing element. The light emitted from the light source unit contains, at least in part thereof, polarized waves that constitute a rotation-symmetric radiating electric field vector distribution in which the electric field vectors have equal magnitudes at equal distances from the center of rotation symmetry. The electrically conductive scatterer has, in the light-receiving portion thereof that receives the light from the light-condensing element, rotation symmetry of order three or more.
