Patent attributes
The present invention is to provide alight emitting module that improves the positional precision of a semiconductor laser diode. A light emitting module of the present invention is configured with a semiconductor laser diode having a facet which inputs, or outputs light; an integrated circuit which is electrically connected to the semiconductor laser diode; and a package which mounts the semiconductor laser diode and the integrated circuit therein. The semiconductor laser diode is mounted on the integrated circuit, and the integrated circuit has a marker. The marker is utilized in determining a position of the semiconductor laser diode with respect to the integrated circuit, and further in determining a position of the semiconductor laser diode with respect to the package.
