<p>The circuit has a light guide (6) with truncated cones having inner volumes (104, 204) and outer volumes (105, 205), respectively. The inner volumes have surfaces (101, 201) on a side of a photosensitive element, surfaces (103, 203) situated on a side of a light input face and lateral surfaces (102, 202), respectively. The outer volumes surround the inner volumes on a part of the lateral surfaces, where the surface (101) has an area smaller than an area of the surface (103). The area of the surface (103) is smaller than the cones. An independent claim is also included for the production of an integrated circuit.</p> |
