An optical modulating device includes a light generator(11), a first optical modulator(12), a second optical modulator(13), and a bias controller. The first optical modulator turns on/off light generated by the light generator according to a reference clock signal to modulate the light into an optical pulse signal with a predetermined period. The second optical modulator turns on/off the optical pulse signal output from the first optical modulator according to data to be modulated to modulate the optical pulse signal into an optical output signal with the data loaded thereon. The bias controller applies a first low-frequency RF signal with a first bias voltage to the first optical modulator, applies a second low-frequency RF signal with a second bias voltage to the second optical modulator, detects a fourth harmonic component of the first RF signal from the optical output signal of the second optical modulator and controls the first bias voltage and the second bias voltage such that the fourth harmonic component has a minimum current.
