Abstract
There is provided is a semiconductor laser device capable of simplifying fabricating processes with a simple construction and easily mounting two semiconductor laser elements and a monitoring PD on a compact package and a wire bonding method for the semiconductor laser device. There are provided a stem provided with a plurality of lead pins through , a sub-mount that is die-bonded onto the stem and has its surface formed integrally with a monitoring PD and two semiconductor laser elements and that are die-bonded onto the sub-mount and have emission light monitored by the monitoring PD . A first bonding surface i.e. anode electrode of the monitoring PD and a second bonding surface i.e. end surface of a lead pin that is approximately perpendicular to the first bonding surface are wire-bonded to each other.
