英文摘要 | PURPOSE:To provide a compact and inexpensive semiconductor light-emitting device which can couple light emitted from an LD chip with a light-receiving element and which has a high reliability, by providing an opening in a stem for taking out light emitted from the LD chip and disposing a spherical lens in this opening. CONSTITUTION:A cap, which is provided with a window for taking out light emitted from the upper end face of an LD chip 12 so as to use the light for a signal, is attached to a stem 1 The stem 11 is provided with an opening for taking out emitted light so as to use the light for control, and a spherical lens 15 is fixed in the opening with a brazing material in a hermetically sealed manner. The spherical lens 15 is fixed at a predetermined distance from the end face of the LD chip, and the distance is previously calculated such that the lens can focus the light on and couple the light to a light-emitting element 14. Thus, since the section for mounting the LD chip 12 and the opening for taking out emitted light for control are provided integrally in the stem 11 with a high precision, the LD chip 12 as well as the spherical lens 15 can be positioned accurately. |
