Abstract
A semiconductor laser module has a stem base and a stem block provided thereon. A submount is fixed on the block, and a laser diode (LD) is mounted on the submount. Transmission lines are formed on the submount and connected to the anode and cathode of the LD. Lead pins extend through the stem base to be connected to the transmission lines. A photodetector is disposed, below the LD, on the stem base. Aperture for placement of the photodetector is formed in the submount, and the photodetector is placed at least partially in this aperture.
