<p>PROBLEM TO BE SOLVED: To provide an integrated type optical multiplying modulation device which has an improved response speed when turning on/off or modulating a high frequency signal because a distance between a filter and a modulator can be shortened by especially miniaturizing a device as to the optical multiplying modulation device capable of easily providing a higher-order sideband wave even from a high frequency signal having small amplitude as compared with conventional phase modulation constitution having a high modulation index. SOLUTION: In a device having constitution for obtaining a sideband wave of high order by leading a laser beam into a kind of a light reflecting resonator and modulating the light plural times during the going and returning of the light in the resonator, a band limiting filter for passing only a sideband wave more than the order of a required sideband wave, a 1st reflection means, an optical modulator and a 2nd reflection means are integrally formed on the same substrate. Consequently, a miniaturized optical multiplying modulation device having a high response speed can be obtained.</p> |
