  • Patent number: 10139275
    Abstract: Apparatus for spectrometrically capturing light includes a wavelength-adjustable filter for converting spectral information into location information and an organic photodiode for converting the location information into electrical signals which can be forwarded, wherein the filter and the organic photodiode form a one-piece monolith, the organic photodiode is connected to the filter or the organic photodiode is integrated in the filter, the filter consists of at least one spectrally resolving element in the form of at least one layer-like photonic crystal which constitutes the monolith and in which two layers of variable thickness D are formed along a direction perpendicular to the incidence of light. A resonant layer is arranged between the two layers. The organic photodiode includes: a photoactive layer, a first electrode, and a second electrode sandwiching the photoactive layer, and one of the electrodes is in contact with the photonic crystal.

  • Patent number: 10036839
    Abstract: A direction-selective interferometric optical filter for spectrometric devices, at least includes an arrangement of two layered one-dimensional photonic structures. Each of the two structures contains a defect layer, and each photonic structure has a dispersion function in the energy momentum space (E, kx, ky), wherein kx and ky are momentum components of transmitted photons of the photonic structures for a defined energy (frequency/wavelength) E in the energy momentum space. Both photonic structures have opposite interfaces which are at a plane-parallel distance from one another. In this case, the dispersion functions of both photonic structures cross or intersect in the energy momentum space and produce a cut set of rays of waves on the surfaces of the dispersion functions at a particular energy, wherein a ray of waves contains waves selectively chosen through the filter at an angle, while other waves are reflected by the filter at other angles.

  • Patent number: 10012541
    Abstract: An optical filter element for devices for converting spectral information into location information, uses a connected detector for detecting signals. The element has at least two microresonators, each comprising at least two superposed reflective layer structures of a material layer having a high refractive index and a material layer having a low refractive index in an alternating sequence, and at least one superposed resonance layer arranged between the two superposed reflective layer structures. The filter element comprises at least one transparent plane-parallel substrate for optically decoupling the two microresonators; the first microresonator being located on a first of two opposing surfaces of said substrate, and the second microresonator being located on said substrate on a second surface thereof that lies opposite the first surface.
