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： A diffractive optical element has a diffraction grating formed by periodic depressions and projections on the surface of a substrate and a dielectric multilayer film on the diffraction grating. The materials of the respective layers of the film are chosen such that the depth of the depressions is an integral multiple of the sum of the thickness of the layers in one period of the film. As a result, individual layers of the film are continuous across multiple depressions and projections, to provide improved first-order reflectance.

摘要： An optical waveguide is produced by forming on a substrate a waveguide layer and/or a clad layer containing, as their main ingredient, polyimide with a fluorine substitution rate of 30% or higher (thus as a fluorinated polyimide layer), with a primer layer laid in between that contains, as its main ingredient, polyimide with a fluorine substitution rate of 10% or lower (including 0%). This improves adherence of the fluorinated polyimide layer to the substrate and prevents the fluorinated polyimide layer from peeling off the substrate. For more effective prevention of such peeling-off and of warping of the substrate, the primer layer is preferably formed to have a thickness of 0.1 to 20 &mgr;m. The primer layer may contain a coupling agent.

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 method of manufacturing a near field light generating device is provided. A photoresist layer is formed on a transparent layer (123). Then, illumination light (L2) directed from the side of solid immersion lenses (11) passes through first openings (122a) and the transparent layer (123) to reach and expose the photoresist layer. After development of the photoresist layer, exposed parts of the photoresist remain as microscopic resist regions (MR) in positions corresponding to the first openings (122a). After a second opaque layer (124) is formed on the transparent layer (123) and the microscopic resist regions (MR), the microscopic resist regions (MR) are removed by a lift-off method to form second openings (124a) in the second opaque layer (124). The first openings (122a) are thus used as a photomask to form the second openings (124a). Therefore, a large number of microscopic openings (MO) having good product quality are formed accurately and easily as the near field light generating device.
