Abstract:
An optical modulation device includes: an optical modulator; an insulating layer; an RC circuit including a resistor and a capacitor connected in series; a bonding wire connected between the optical modulator and the RC circuit; a first metal layer provided on the insulating layer; and a second metal layer that has a width larger than that of the first metal layer and is provided on the insulating layer, the second metal layer being connected with a ground potential and being connected to the RC circuit via the first metal layer.
