| 英文摘要 | PURPOSE:To prevent crosstalk between photo detectors by a method wherein two beams outputted from a pair of lasers are introduced into different photo detectors through different optical waveguides, and independently detected. CONSTITUTION:A mount 5 side (laser 1 side) and a mount 6 side (laser 2 side) face each other so as to constitute a pair. The beam of the laser 1 is outputted from an active layer 3 upward and downward. The beam outputted downward enters an optical waveguide 9 from a surface 32, reflected by an obliquely processed surface 33, and enters the light receiving surface 35 of a photo detector 1 The beam of the laser 2 is similarly detected by the other photo detector. In this manner, two beams outputted from a pair of semiconductor laser chips are introduced by different optical waveguides respectively and detected by a pair of photo detectors. |
