Abstract: The present invention has an object to provide an optical modulation device and an optical modulation method that achieve an excellent spectral efficiency with a simple and compact configuration and low power consumption. An optical modulation device according to an exemplary aspect of the present invention includes a CW light source (11), a coupler (12), optical modulators (14a) and (14b), an optical frequency shifter (15b), a serial-to-parallel converter (21), and a delay circuit (24a). The serial-to-parallel converter (21) divides a data signal having a bit rate B into two data strings having a bit rate B/2, and extracts a clock signal (CLK). The delay circuit (24a) temporally synchronizes the two data strings. CW light emitted from the CW light source is split into two beams by the coupler (12). The optical modulators (14a) and (14b) generate optical signals by modulating the two split light beams according to the data strings. The optical frequency shifter (15b) shifts center frequencies of the optical signals by Δf=B/(2×2) according to the clock signal (CLK).
