摘要:
An optoelectronics device wherein a light-receiving element which defines a monitor light receiver and a semiconductor laser which generates a laser beam are hermetically sealed in the same package, and wherein the light-receiving surface of the element for measuring the output power of the beam of light emitted from the semiconductor laser is disposed so as to be inclined with respect to the light-emitting surface of the semiconductor laser. The wire bonding surface of the light-receiving element pellet-bonded to a stem and the wire bonding surface of the lead electrically connected to the light-receiving element through a wire are arranged so as to be parallel with each other. Thus, it is possible to support both the bonding surfaces horizontally at the same time. As a result, a bonding tool can be brought into perpendicular contact with each of the bonding surfaces, and this enables appropriate wire bonding to be effected.
