摘要： 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.

摘要： A trans-impedance amplifier (TIA) for a light-receiving circuit is disclosed where the TIA reduces the power consumption as suppressing the degradation of the signal quality in high frequency regions. The TIA comprises a primary core, a dummy core, and a differential amplifier that receives each output of two cores in the differential mode. Two cores have an arrangement substantially same to each other except that the power consumption thereof is smaller in the dummy core. Because the output impedance of two cores becomes substantially equal, the scattering parameter of the common mode to the differential mode at the output of the primary core becomes small enough.

摘要： A driver circuit for the laser diode is disclosed. The driver circuit has the shunt configuration with a switching transistor connected in parallel to the laser diode to shunt the current flowing in the laser diode. In the present invention, the bias for the switching transistor is varied as the operating temperature of the laser diode. In addition, the gate bias for the switching transistor is compensated for the temperature dependence of the switching transistor.
