Abstract
An optical communication device is configured to include: a laser diode that outputs light; an EA modulator including a cathode and an anode, to modulate the light output from the laser diode on the basis of a high-frequency signal applied between the cathode and the anode; a resistor connected between the cathode and the anode; and a pattern line connected in series with the resistor and having an inductance component, in which each of the laser diode and the EA modulator is formed on a front surface of the high-frequency line substrate or a back surface of the high-frequency line substrate, and the pattern line is formed on a side face of the high-frequency line substrate.
