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.

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.

Abstract: An organic photodetector for detecting infrared, visible and ultraviolet radiation is provided with a tunable spectral response to achieve a high responsivity at different design wavelengths. The organic photodetector comprises at least a substrate, a first electrode, a second electrode and at least one organic material, which is arranged between the first and the second electrodes, wherein a Schottky barrier is formed at the interface between the first electrode and the organic material and/or at the interface between the second electrode and the organic material. The tunability in the responsivity of the organic photodetector is achieved by structuring at least one electrode so that it comprises nano-apertures for exciting surface plasmon resonances.

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. The resonance layer of at least one microresonator, and/or the reflective layer structure that surrounds said resonance layer, has a layer thickness which can vary along a horizontal axis of said filter element.
