Patent ID: 7782915

Claim:
A light emitting module, by receiving an electric signal, for emitting an optical signal corresponding to the received electrical signal, comprising: a semiconductor laser diode for emitting the optical signal, the semiconductor laser diode being an edge-emitting diode having a front facet and a rear facet; an integrated circuit configured to receive the electrical signal to drive the semiconductor laser diode, the integrated circuit integrating at least one transistor and being made of silicon with a marker provided thereon to determine a position of the semiconductor laser diode relative to the integrated circuit, the integrated circuit providing a groove extending from an edge thereof toward a center portion of the integrated circuit; and a package configured to enclose the semiconductor laser diode and the integrated circuit therein, the package including a disk-shaped stem and a cylindrical-shaped lens cap connected to the stem to define a space that encloses the semiconductor laser diode and the integrated circuit therein, the stem including a sub-mount with a side surface extruding from a primary surface of the stem, wherein the integrated circuit has a thickness smaller than 300 μm, the integrated circuit is mounted on the side surface of the sub-mount and the semiconductor laser diode is directly mounted within the groove on the integrated circuit in such a manner that the front facet is arranged along the edge of the integrated circuit, and the integrated circuit is a shunt driver configured with a driving transistor connected in parallel to the semiconductor laser diode.
