摘要: A modulation light signal generating device utilizing the mechanism of a multiplication light modulation device, and a modulation signal generating device using the modulation light signal generating device and capable of outputting millimeter waves. The modulation light signal generating device (1) comprises a light modulator (2), a first optical filter (3), and a second optical filter (4), wherein the frequency of a modulation signal input to the light modulator is controlled to thereby control the frequency of a multiplication modulation light output from the second optical filter.
