| 英文摘要 | PURPOSE:To control optical outputs from two semiconductor laser arrays separately by arranging at least one light-receiving surface of a photo-diode at double levels and similarly forming the outgoing edge of a corresponding semiconductor laser chip at double levels. CONSTITUTION:Main laser beams are emitted from outgoing edge faces on the left sides of waveguides 2, 3. On the other hand, laser beams for monitor radiated from the outgoing edge face of the waveguide 2 in laser beams for monitor emitted from outgoing edge faces on the right sides are separated by the light-receiving surface 13a of a photo-diode chip 12a and laser beams for monitor radiated from the outgoing edge face of the waveguide 3 by the light-receiving surface 13b of a chip 12b respectively and received. Since a stepped section is formed to the outgoing edge face on the right side, laser beams for monitor from the waveguide 2 are received effectively only by the light-receiving surface 13a, and hardly projected to the light-receiving surface 13b of the diode 12b. Likewise, laser beams for monitor from the waveguide 3 are hardly projected to the light-receiving surface l3a. Accordingly, when outputs from the chips 12a, 12b are used for control, optical outputs from two laser arrays can be controlled separately. |
