  • Patent number: 9209327
    Abstract: A pixel is formed in a semiconductor substrate (S) with a plane surface for use in a photodetector. It comprises an active region for converting incident light (In) into charge carriers, photogates (PGL, PGM, PGR) for generating a lateral electric potential (?(x)) across the active region, and an integration gate (IG) for storing charge carriers generated in the active region and a dump site (Ddiff). The pixel further comprises separation-enhancing means (SL) for additionally enhancing charge separation in the active region and charge transport from the active region to the integration gate (IG). The separation-enhancing means (SL) are for instance a shield layer designed such that for a given lateral electric potential (?(x)), the incident light (In) does not impinge on the section from which the charge carriers would not be transported to the integration gate (IG).

  • Patent number: 9121759
    Abstract: Disclosed is an arrangement for detecting first light (L1) and second light (L2), with the first light (L1) and second light (L2) having no wavelength in common. The arrangement includes a first effective detector area (D1) and a second effective detector area (D2). The first effective detector area (D1) is exposed to the first light (L1) and/or second light (L2) different from the first light (L1) and/or second light (L2) to which the second effective detector area (D2) is exposed when the arrangement is exposed to spatially uniformly distributed first light (L1) and second light (L2). The difference between the first light (L1) and/or second light (L2) to which said first detector area (D1) and second detector area (D2) are exposed to can be a difference in intensity and/or difference in an angle of incidence relative to the arrangement.

  • Patent number: 9094593
    Abstract: Optoelectronic modules include an optoelectronic device and a transparent cover. A non-transparent material is provided on the sidewalls of the transparent cover, which can help reduce light leakage from the sides of the transparent cover or can help reduce stray light from entering the module. The modules can be fabricated, for example, in wafer-level processes. In some implementations, openings such as trenches are formed in a transparent wafer. The trenches then can be filled with a non-transparent material using, for example, a vacuum injection tool. When a wafer-stack including the trench-filled transparent wafer subsequently is separated into individual modules, the result is that each module can include a transparent cover having sidewalls that are covered by the non-transparent material.

  • Patent number: 9091568
    Abstract: An optical encoder system includes a module that has a light emitting element and a light detecting element, wherein the light detecting element is operable to detect light at a wavelength emitted by the light emitting element. The optical encoder system also includes a code wheel that has facets on its surface. Each facet has a surface that provides diffuse reflectance, with adjacent facets being inclined by different amounts. The code wheel can be disposed with respect to the module so that at least some light emitted by the light emitting element is reflected by the facets back toward the module, wherein an amount of reflected light detected by the light detecting element in the module depends at least in part on the rotational position of the code wheel.
