| description | The utility model discloses a beam splitting device and a quantum light source. The beam splitting device comprises a first beam splitter and a second beam splitter, wherein the first beam splitter splits light waves into a first light beam and a second light beam; the second beam splitter is used for outputting light waves; the first waveguide and the second waveguide are used for communicating the first beam splitter with the second beam splitter, and the first beam of light is transmitted to the second beam splitter through the first waveguide; the second beam of light is transmitted to a second beam splitter through a second waveguide; the length difference between the second waveguide and the first waveguide is delta L; the heater is arranged on the second waveguide; the second waveguide and the heater are used for adjusting the phase of the light wave, so that the TE polarized wave in the light wave is emitted from the first output waveguide, and the TM polarized wave in the light wave is emitted from t |
