ABSTRACT:
A circuit for exciting an optical modulator, in accordance with the present invention, includes an optical modulator for modulating an optical signal, a first strip line electrically connected to the optical modulator and directing a modulation RF signal to the optical modulator, and a second strip line electrically connected to the first strip line through the optical modulator. The first strip line includes a first electrical device and has a first characteristic impedance, the second strip line includes a second electrical device and has a second characteristic impedance, the first characteristic impedance is equal to a characteristic impedance of a path through which the modulation RF signal is input into the first strip line, and a parallel-combined impedance of the first and second electrical devices is equal to the characteristic impedance of the path.
