Patent number: 6242760Abstract: An object is that stray light carriers are absorbed, and hence a signal larger than actual signal will not be outputted, thereby to output more precise signals. For achieving the foregoing, a concave portion is provided on the surface of a semiconductor substrate, a light receiving element for signal detection is provided around the concave portion, a semiconductor laser element is mounted in the concave portion, and a light shielding area is provided on the side existing between the semiconductor laser element and the light receiving element for signal detection of the sides of the concave portion. This causes stray light contained in the light emitted from the semiconductor laser element to be cut off at the light shielding area. Consequently, around the light receiving element for signal detection, the occurrence of stray light carriers on the surface of the semiconductor substrate can be prevented, and hence the stray light carriers are not absorbed by the light receiving element for signal detection.Type: GrantFiled: July 12, 1999Date of Patent: June 5, 2001Assignee: Matsushita Electronics CorporationInventors: Shin-ichi Hamaguchi, Yuzo Shimizu, Toru Tsuruta, Masanori Hirose
