| 摘要 |
The present invention provides an optical transmission device 100 capable of solving the problem of an unnecessary residual sideband components to thereby obtain a high-quality optical intensity-modulated signal in a case where an SSB optical modulation section 20 has wavelength dependence and a manufacturing error. In the optical transmission device 100 , where the SSB optical modulation section 20 cannot evenly branch the intensity of the optical carrier into two routes of optical waveguide, the amplitude adjusting section 62 adjusts the amplitude of an electric signal that changes the refractive index of the SSB optical modulation section 20 so that the unnecessary sideband component of the optical intensity-modulated signal outputted from the SSB optical modulation section 20 disappears.
