  • Patent number: 11480495
    Abstract: The invention relates to a contacting module (1) by means of which the individual electrical and optical inputs and outputs (AoC) of optoelectronic chips (2) are connected to the device-specific electrical and optical inputs and outputs of a test apparatus. It is characterized by a comparatively high adjustment insensitivity of the optical contacts between the chips (2) and the contacting module (1), which is achieved, for example, by technical measures which result in the optical inputs (EoK) of the chip (2) or on the contacting module (1) being irradiated in every possible adjustment position by the optical signal (So) to be coupled in.

  • Patent number: 11391959
    Abstract: Techniques are provided for laser illumination employing closely spaced laser beams. A system implementing the techniques according to an embodiment includes a semi-cylindrical optical block comprising a curved surface and a planar surface. The system further includes two laser sources configured to direct first and second laser beams to the curved surface, such that the first laser beam enters and exits the block parallel to and offset from the planar surface by a selected translation distance, and the second laser beam enters the block at a critical angle relative to the planar surface. The critical angle is associated with total internal reflection of the second laser beam along the planar surface, such that the second laser beam exits the block parallel to, and separated from, the first laser beam exiting the optical block. The separation of the exiting first and second laser beams is controlled by the selected translation distance.
