| 英文摘要 | PURPOSE:To enable Im of a monitor PD after assembly to be reduced and a heat sink block on assembly to be positioned by forming a monitor PD mount part for both recessed and projecting types on the upper surface of a stem. CONSTITUTION:A monitor PD chip 4 is soldered to a monitor PD mount part 6 of a stem 5 of both recessed and projecting type. The monitor PD chip 4 is located at the center of the stem 5. Then, a block where a laser chip 1, a submount 2, and a heat sink block 3 are soldered is soldered to the stem 5. At this time, the laser chip 1 is located on the light-receiving surface of the monitor PD chip 4 referring to a projecting part of the monitor PD mounting part 6. Then, the gap between the laser chip 1 and the monitor PD chip 4 becomes wider as compared with the conventional stem having a monitor PD mount part in projecting shape. |
