US Patent 7249897 Optical module

An optical module includes an optical connector on one end of a package for storing a carrier including an optical element, and a laminated ceramic feedthrough disposed on the other end of the package. The feedthrough includes on an outer surface an electrical terminal perpendicular to the optical axis of light incident on and exiting from the optical connector, and includes on its inner surface a chip carrier connection terminal connected to the electrical terminal. A flexible printed circuit board includes a connection pad acting as an electrical terminal at a position corresponding to the electrical terminal of the feedthrough and is fixed to the feedthrough with an anisotropic conductive adhesive.
