摘要： A transmissive diffraction grating includes a substrate and a plurality of ridges provided in a mutually parallel manner at constant periodicity p on the substrate. The ridges include a first layer, a second layer (refractive index n2: 2.0-2.5), and a third layer with non-continuous refractive indices, arranged in that order from the substrate outward. The first layer adjacent the substrate, in terms of its refractive index, exhibits a difference of 0.1 or less relative to the substrate. The second layer has a higher refractive index than the first layer and third layer and satisfies the following conditions. For a single ridge, the cross-sectional area S of a cross-section of the second layer perpendicular to the longitudinal direction of said ridge is in the range of 0.75p2k1θ2/(n2−1)

摘要： An optical element according to the invention constituted by a multilayer structure having a periodic structural portion as at least one region constituted by repetition of a predetermined period, wherein an end surface of the multilayer structure not parallel to layer surfaces of the multilayer structure is used as a light input surface whereas one or each of opposite surfaces of the multilayer structure parallel to the layer surfaces is used as a light output surface. There is an intermediate layer between a medium and a surface of the multilayer structure, the intermediate layer having a refractive index less than the refractive index of the medium. The periodic structural portion of the multilayer structure can be regarded as a one-dimensional photonic crystal. Refracted light from the one-dimensional photonic crystal has good directivity and the direction of the refracted light has strong dependence on wavelength. When this wavelength dependence property is used, a spectroscopic device or a polarized light separating device of high resolution can be achieved without increase in device size.

摘要： A transmission type polarizing element 1 includes a dielectric substrate 3 having a structure in which a plurality of ridges 2 with an angle section are arranged parallel to each other on one side of the dielectric substrate 3, a thin film 4 that is made of a light absorbing substance and formed on the surfaces of the plurality of ridges 2 with an angle section, and a first dielectric substance layer 5 covering the surface of the thin film 4 that faces away from the dielectric substrate 3. When light is incident perpendicularly on the dielectric substrate 3, this transmission type polarizing element 1 transmits a TM polarizing component of the incident light whose magnetic field vibrates in the same direction as the longitudinal direction of the ridges 2 and absorbs a TE polarizing component of the incident light whose electric field vibrates in the same direction as the longitudinal direction of the ridges 2. Thus, a transmission type polarizing element that reduces return light, has high durability, and is capable of being used as a polarizing plate can be provided with a simple configuration.
