OPTICAL ELEMENT MODULE PACKAGE AND MANUFACTURING METHOD THEREOF, ESPECIALLY USING GLASS TYPE SEALING MATERIAL

摘要

PURPOSE: An optical element module package and a manufacturing method thereof are provided to simplify a manufacturing process and to reduce manufacturing costs by using glass type sealing material to fix leads on a metallic stem. CONSTITUTION: An optical element module package of a TO-Can(Trademark) structure includes a laser diode(303), a photo diode(304), a stem(301), and a plurality of leads(302). The laser diode emits an optical signal. The photo diode monitors the optical signal outputted from the laser diode. The stem includes a first penetration hole of a long shape which penetrates both surfaces and is extended in parallel with the direction of a diameter. The plurality of leads are arranged in one row with penetrating the first penetration hole. A sealing material made of glass is filled in the first penetration hole to fix the stem and the leads.
