Abstract
An optocoupler, for converting optical signals into electrical signals and vice versa, includes a package with a jack connector for receiving an optical waveguide. On a lower side of the package, surface-mountable outer contacts are arranged on an interconnection film. A mounting position for semiconductor chips, including one optical semiconductor chip and one application-specific semiconductor chip, is provided in the package on the optical axis of the optical waveguide. The optical semiconductor chip is aligned with the optical axis inside the package. The outer contacts are arranged outside the package on the flexible interconnection film. Between the mounting position and the outer contacts, the interconnection film includes a curved region which is embedded in the package material such that the surface-mountable outer contacts on the lower side of the package are freely accessible.
