The utility model belongs to the technical field of photoelectrons, and discloses an all-optical logic OR gate device, which comprises a waveguide cavity, a reflector is arranged in the middle of thefront side of the waveguide cavity, an input light path is arranged at the front end of the rear side of the waveguide cavity, an output light path is arranged at the rear end of the rear side of thewaveguide cavity, and the reflector is connected with a data input light path. According to the utility model, the whole AND operation is carried out in an optical state without photoelectric conversion; because photoelectric conversion is not needed, the structure is simple, integration is easy, and the size is small; the insertion loss is small and the output optical power is high; an all-optical circuit can be formed to realize all-optical information processing; and the output optical power is stable, and the output fluctuation is not large due to multi-path optical input. 本实用新型属于光电子技术领域，公开了一种全光逻辑或门装置，包括波导腔体；所述波导腔体
