Abstract:
The apparatus includes: an electric circuit including a first transmission line portion that propagates a second differential signal; a second amplifier that amplifies the second differential signal propagated through the first transmission line portion and outputs the amplified second differential signal as a third differential signal; a second transmission line portion that propagates the third differential signal; and an optical modulator including a first optical phase modulation portion that modulates a phase of an optical signal in response to the second differential signal propagating the first transmission line portion, an optical delay portion that delays the phase of the optical signal modulated, and a second optical phase modulation portion that modulates the phase of the optical signal delayed, in response to the third differential signal. The second amplifier has a gain that has a maximum value in a first frequency region of the second differential signal set to be smaller than a minimum value in a second frequency region higher in frequency than the first frequency region.
