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.
