    摘要: In accordance with embodiments of the present invention, a nano-structured optical wavelength transmission filter (1) is provided. The optical filter (1) comprises a patterned substrate (10) on which a high refractive index dielectric waveguide (20) is arranged. A low index dielectric layer (30) is arranged on the high refractive index dielectric waveguide (20), on which an array (40) of metallic nanostructures (42a-42n) is arranged. The layers of the optical filter (1) have conformal shapes defined by patterned surface (10a) of the substrate (10).
    The invention relates also an optical filter system (2) comprising the optical transmission filter (1) and a detector array (3) fixed to the substrate (10). The invention relates also to spectrometer (4) comprising at least one optical transmission filter (1) and/or at least one said optical transmission filter system (2), and has a spectral resolution of lower than 30nm for incident light having a wavelength between 300nm and 790nm.
    The invention relates also to a method of fabrication of an optical filter (1), an optical filter system (2) and a spectrometer (4).

    摘要: The invention concerns a photoelectric conversion device (1) comprising:
    at least one photoconversion element (10) comprising at least one organic photoconversion layer;
    at least a first grating structure (20) arranged on a first side of the photoconversion element;
    at least a second grating structure (30) arranged on a second side of the photoconversion element;
    wherein said at least a first grating structure (20) is arranged so as to direct a near-infra-red light portion of light incident on said first grating structure (20) into said photoconversion element (10), the said at least a second grating structure (30) being arranged to reflect at least a part of said near-infra-red light portion back into said photoconversion element (1) and to pass visible light out of the photoelectric conversion device.
