Abstract:
The photodetector device comprises a substrate (1) of semiconductor material, a sensor region (2) in the substrate, a plurality of grid elements (4) arranged at a distance (d) from one another above the sensor region, the grid elements having a refractive index, a region of lower refractive index (3), the grid elements being arranged on the region of lower refractive index, and a further region of lower refractive index (5) covering the grid elements.
