| 英文摘要 | PURPOSE:To control each laser-beam output respectively by making each photodiode for light reception to correspond so as to coat a waveguide isolation groove formed for receiving laser beams for monitor so as to separately cross each waveguide and mounting photodiode chips. CONSTITUTION:Waveguide separation grooves 11, 12 are shaped to one parts of each waveguide 2, 3 so as to cross respective waveguide 2, 3, and photodiode chips 18, 19 are set up onto the waveguide separation grooves 11, 12 so as to coat the waveguide separation grooves 11, 12, using one surfaces formed to these waveguide separation grooves 11, 12 as the edge faces of a resonator and the other surfaces as reflecting surfaces. Consequently, laser beams for monitor epitted from the edge faces of the resonator in each waveguide separation groove 11, 12 do not interfere with adjacent respective laser beam, and can be projected to the light-receiving surfaces 18, 19 of each photodiode for the photodiode chips. Accordingly, laser beam outputs from a semiconductor laser array device can be controlled separately by laser beams for respective monitor. |
