Abstract:
In order to provide an optical modulator capable of controlling a bias voltage to correspond to transmission characteristics of a modulation means even when a multi-level modulation scheme is applied, an optical modulator  10  is provided with: an amplitude information control means  20  that generates amplitude information for controlling the amplitude of an information signal to correspond to transmission characteristics of a modulation means  50,  adds a dither signal to the amplitude information, and outputs the amplitude information; a bias value control means  30  that generates and outputs a bias value for controlling the center of the amplitude of the information signal to correspond to the transmission characteristics of the modulation means  50;  a data output means  40  that corrects the amplitude of information data on the basis of the amplitude information, and outputs the information data as the information signal; the modulation means  50  that corrects the center of the amplitude of the information signal on the basis of the bias value, modulates continuous wave light by using the information signal, and outputs a modulation signal; and an adjustment means  60  that extracts, from the modulation signal, the dither signal added to the amplitude information, and adjusts the amplitude information and the bias value such that the differential value of the intensity of the dither signal added to the amplitude information becomes zero.

Claim (Index 9):
