Abstract:
A semiconductor optical modulation device includes a semiconductor optical modulator, wires, an output side line, an input side line and a resistor. The semiconductor optical modulator is an electroabsorption optical modulator. One of the wires is connected between an electrode of the semiconductor optical modulator and the input side line. The other of the wires is connected between the electrode of the semiconductor optical modulator and the output side line. The resistor is connected in series with the output side line. Impedance of the output side line and impedance of the resistor are different from each other.
