Abstract
A light-transmitting module of the present invention includes a light-emitting device such as a laser diode (LD), a transistor for shunting-drive the LD and a CAN type package with a base and an electrically conductive block. The LD and the transistor are mounted on a side of the block in side-by-side arrangement such that the LD substantially positions a center of the package. One of the current terminals of the transistor and one electrode of the LD are connected via the conductive block. The other of the current terminal of the transistor and the other of the electrodes of the LD are connected to one lead, while the control terminal of the transistor is connected to the other lead. Since the present module includes the transistor within the CAN type package, the size thereof may be miniaturized, and the quality of the optical output can be enhanced.
