摘要： In an optical element, a propagation direction of incident light beam is largely changed and the direction-changed light beam is derived in a desirable direction without increasing a dimension and manufacturing cost thereof. The optical element includes photonic crystal having a refractive index which changes periodically depending on a location of the photonic crystal, wherein an angle defined between a first end face and a second end face thereof is determined in such a manner that a light beam incident upon the first end face at a predetermined incidence angle and having a predetermined wavelength is emitted from the second end face in a desirable direction.

摘要： A solid state imaging device has a semiconductor substrate with photodiodes and charge transfer sections formed thereon, transfer electrodes formed on the charge transfer sections across an insulating layer, and a light shielding layer to protect the charge transfer sections from light. The light shielding layer has openings to correspond the positions of the photodiodes. Disposed above the openings of the light shielding layer are microlenses, and a converging structure such as a converging lens is provided inside each opening. Incident light rays from the microlens are focused toward the photodiode effectively by the converging lens.

摘要： A sensor is an optical resonator constituted by: a first reflecting body that exhibits semi transmissivity/semi reflectivity; a transparent body; and a second reflecting body that exhibits one of reflectivity and semi transmissivity/semi reflectivity, provided in this order from the light incident side. The sensor is configured such that the absorption peak of the measuring light beam by resonance in the optical resonator matches the absorption peak of the measuring light beam by local plasmon resonance generated at the surface and/or within the optical resonator. The sensor has absorption properties such that light of specific wavelengths are absorbed depending the mean complex refractive indices of the first and second reflecting bodies and the thickness of the transparent body. An emitted light beam is output from the first reflecting body. The physical properties of the emitted light beam that change according to the absorption properties are detected.
