Abstract: A photodiode device including a photosensitive diffusion junction within a single layer. The photodiode device further includes a resonant grating located within the single layer. The photosensitive diffusion junction is located within the resonant grating.

Abstract: The invention relates to a method for producing an active optical connection with an optoelectronic element and a light deflection means for light deflection between the optoelectronic element and an optical waveguide arranged transversely with respect to the beam direction of said element. In this case, it is provided that a carrier substrate for the optoelectronic element is arranged in a highly precisely repeatably positioning machine, in particular a flip-chip machine, the optoelectronic element is mounted on the substrate by a or the highly precisely repeatably positioning machine and a curable, moldable compound is applied over the optoelectronic element, and the moldable compound is molded by a mold for molding light deflection means, said mold being moved by a or the highly precisely repeatably positioning machine, and at the earliest thereafter the substrate is removed from the or a highly precisely repeatably positioning machine.

Abstract: The invention relates to an element for the combined symmetrization and homogenization of a beam of rays and to a method for designing an element of this type. One object of this invention is to propose an element and a corresponding design method by means of which a beam of rays with any desired intensity distribution is shaped from a beam of rays with an inhomogeneous intensity distribution. In particular, the intention is to transform a beam of rays with an elliptical intensity distribution into one with a different elliptical intensity distribution. For this purpose, the invention provides a phase element for the simultaneous circularization and homogenization of anisotropic intensities of electromagnetic waves.

Abstract: A method for establishing an optical connection between at least one optoelectronic component arranged in a first substrate and emitting or receiving optical radiation substantially perpendicular to a substrate surface of the first substrate, and at least one optical waveguide aligned with a first end substantially parallel to the substrate surface. The method comprises providing a second substrate that is transparent for at least one wavelength range of the optical radiation, and applying a layer of material on the second substrate. The layer is transparent, at least after structuring, for the wavelength range.

Abstract: An optical arrangement permutes elements of a multi-dimensional array by projecting an input element array onto an output via a plurality of optical paths. Each optical path provides a relative shift in its projection on the output plane whereby there is a prescribed permutation of elements.

Abstract: An arrangement for modifying an information carrying radiant energy beam array in which occurrences of a first prescribed pattern of radiant energy beams in the array are detected by producing images of said beam array and shifting the images relative to each other responsive to a first prescribed pattern. The shifted images are superimposed and a radiant energy beam array is formed that identifies the occurrences of first prescribed patterns in the superimposed images. A plurality of images of the identifying beam array are produced and shifted relative to each other in accordance with a second prescribed pattern. The shifted images of said occurrence identifying beam array are superimposed to form the modified beam array. The modifications may comprise arithmetic processing, pattern or image processing or Turing machine type processing.
