Abstract

PURPOSE:To improve the position accuracy between a light emitting element and a photodetector by providing a submount on a stem, and forming the photodetector on part of the mount. CONSTITUTION:A submount 2 is secured to the center on the upper surface of a metal stem 1. The submount 2 is formed of a semiconductor substrate 4, and a P-N junction 7 for a photodetector is formed on the part of a main surface 5. The main surface of the submount 2 is covered with an insulating film 9 except the contact 8 for the anode of the photodetector. On the other hand, a wiring pattern 18 which secures a light emitting element 17, is formed on the flat film 9 of the submount 2. A metal cap 29, on which a transparent glass plate 28 is mounted at the center, is covered on the stem 1. In this manner, the light emitting element and the photodetector can be simply assembled while maintaining the positional relationship accurately.
