    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 polarization conversion optical system converts light having a nonuniform plane of polarization into light having a uniform plane of polarization. The system includes a multilayer dielectric film at the side upon which the target light is incident. The film exhibits the property that it reflects one polarized component of the light and transmits a second polarized component of the light at a first angle of incidence, but transmits the first component at a second angle of incidence. Incident target light that is transmitted through the film at the first angle of incidence passes through a quarter-wavelength plate and is reflected at the second angle, whereupon it is retransmitted through the quarter-wavelength plate to be converted from one plane of polarization to the other. It is then emitted from the dielectric film in the same plane of polarization as light reflected by the film.

    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： A rising mirror is constructed by forming on a glass substrate a first region and a second region having different reflection properties. The first region is formed of, for example, an antireflection film, and the second regions is formed by superimposing a phase adjustment layer for adjusting the phase of reflected light and a dielectric multilayer film in this order. Forming the phase adjustment layer on the glass substrate in this manner permits, for example, phase adjustment such as eliminates phase shift in reflected light between the regions, and phase adjustment such as cancels out phase shift caused by the objective lens of the optical disc, thereby permitting suppressing disturbance in the wave front of reflected light as whole.

    摘要： On the surface of a plastic base, there are formed, from the base side, an adhesion layer, a reflective layer formed mainly of Ag, and a protective layer formed of a light-transmitting dielectric layer. The adhesion layer is formed of a layer of a mixture of aluminum oxide and lanthanum oxide, and is given a thickness in the range from 10 nm to 120 nm. To further enhance the adhesion between the base and the Ag layer, and to surely prevent entry of moisture or the like from the base into the Ag layer, the mix proportion of lanthanum oxide in the adhesion layer is preferably kept in the range from 60% to 80% by weight.
