An adiabatic coupling phase modulation module has an optical substrate, an asymmetric adiabatic coupling polarization beam splitter and two electro-optical phase modulators. The asymmetric adiabatic coupling polarization beam splitter performs band spatial filtering on a quantum light source signal to output a light source signal of a specific wavelength band, and performs polarization spatial filtering on the light source signal of specific wavelength band to output a first orthogonal polarization direction light source signal of the specific wavelength band and a second orthogonal polarization direction light source signal of the specific wavelength band. The two electro-optical phase modulators respectively perform phase coding processes on the first orthogonal polarization direction light source signal and the second orthogonal polarization direction light source signal.
