A driver for an EA-DFB device includes a switching device. The EA-DFB device is put between a positive power supply and a negative power supply as connected in series to a bias current source and the switching device. The EA device is modulated by the switching device in the differential mode. The switching device includes paired transistors each having a load, one of which is a resistor connected in parallel to the EA device, while, the other is constituted by a resistive element. |
