Abstract
The present invention provides an optical transmitting module or optical transmitting sub-assembly in which an inductor for de-coupling the bias circuit of the semiconductor laser diode is built. The laser diode is mounted on the side surface of the block provided on the stem, while the inductor is installed on the lead, which is secured by the stem, such that one electrode of the inductor is in contact to the lead and the other electrode of the inductor is connected to an electrode of the laser diode. The electrode of the laser diode is also connected to the other lead. Thus, the electrode of the laser diode is connected to two leads, one of which is through the inductor.
