Abstract:
1. An optocoupler for converting optical signals into electrical signals and vice versa, the optocoupler comprising: a package including: surface-mountable outer contacts arranged, outside the package, on a portion of the flexible interconnection film disposed on a lower side of the package; semiconductor chips, including an optical semiconductor chip and an application-specific semiconductor chip with an integrated circuit, the semiconductor chips being disposed inside the package; and a mounting position for the semiconductor chips, the mounting position being arranged in the package on an optical axis of the optical waveguide, the optical semiconductor chip being aligned with the optical axis, wherein the optical semiconductor chip is mounted, in the region of the optical axis and in the direction of the optical waveguide, on an upper side of the flexible interconnection film, and the application-specific semiconductor chip is mounted on an opposite lower side of the flexible interconnection film; wherein the interconnection film comprises, between the mounting position and the outer contacts, a curved region embedded in the package such that the surface-mountable outer contacts on the lower side of the package are freely accessible.
