| Zusammenfassung: | PURPOSE:To obtain high isolation and also to further more facilitate the optical connection between each port and an optical waveguide. CONSTITUTION:This circulator is provided with first and second double refractive crystal plates 5, 6 being arranged by keeping a specified space along the advancing direction of light beams, a reciprocal rotor 8 and a non-reciprocal rotor 7 being inserted between the first and second double refractive crystal plates 5, 6 and the reciprocal rotor 8 and the non-reciprocal rotor 7 being rotated an electric field vibration plane of the light beams by the equal angle is provided and also the directions of each crystal axis of the first and second double refractive crystal plates 5, 6 are characterized by being coincided mutually. |
