英文摘要 | PURPOSE:To obtain a semiconductor laser device which is composed of a less number of components and facilitates reduction of a position adjustment work at a low cost by a method wherein a monitoring photodiode and a signal reproducing photodiode are assembled in a submount with high position accuracy. CONSTITUTION:A signal reproducing photodiode 14 and a monitoring photodiode 4 are formed on the same plane of a submount 16 which is a thermal stress relieving member. An incident light is reflected by a beam splitter 17 provided on the signal reproducing photodiode 14 to the direction opposite to the signal reproducing photodiode 14 and introduced into the monitoring photodiode 4 by a mirror 18 provided on the monitoring photodiode 4. Further, a laser diode chip 1 which emits a laser beam is provided at a required position on a level same as or higher than the plane of the submount 16 on which the signal reproducing photodiode 14 and the monitoring photodiode 4 are formed. With this constitution, the number of components for a pickup device can be reduced, the size can be reduced and the cost can be saved. |
