| 英文摘要 | PURPOSE:To obtain a semiconductor light-emitting device in which the optical axis of emitted light can be easily aligned and which is still simple and inexpensive, by providing spherical lenses in openings provided in a cap for the purpose of taking out light emitted from the end faces of an LD chip. CONSTITUTION:A stem 5 has a stud 5-1 disposed eccentrically to the right-hand side. An LD chip 1 is bonded to the right-hand end of the stud. Spherical lenses 7 and 8 are hermetically fixed in holes provided therefor on the side faces of a cap 6, respectively. When the cap 6 is welded to the stem 5, each of the spherical lenses 7 and 8 is arranged such that they can receive light from the LD chip 1 at the center thereof. The distance l1 from the end face of the LD chip 1 to the spherical lens 7 and the distance l2 from the other end face of the spherical lens 7 to an optical fiber 8 are previously calculated, so that the device is designed based on these distances. Further, light emitted to the left-hand side for providing a control signal is also coupled to the light-receiving element 10 through the spherical lens 8. |
