Abstract:
A high frequency laser module comprisinga micromechanically structured silicon substrate for mounting optical components thereon, said micromechanically structured silicon substrate being made by etching a silicon substrate with an etching mask; a metallic mounting layer arranged on one side of said silicon substrate; a laser diode mounted on a region of said metallic mounting layer and in direct electrical contact with said metallic mounting layer; high-frequency wiring arranged on said one side of said silicone substrate and spaced from said laser diode in a horizontal direction on said silicone substrate, said high-frequency wiring comprising a ground conductor and a hot conductor separated from each other by a dielectric layer, wherein said metallic mounting layer is structured to form said ground conductor and said region on which said laser diode is mounted, and wherein said region is electrically connected with said hot conductor; and an insulating layer sandwiched between said metallic mounting layer for said laser diode and said silicone substrate, said insulating layer being formed to act as said mask for etching the silicon substrate.
