摘要： An optical circulator has a first collimator; a first block of birefringent material; a first compound polarization rotator; a light angle deflector (e.g., Wollaston prism); a second compound polarization rotator; a second block of birefringent material; and a second collimator. Light from the first fiber exits the first collimator along a first path into a first collimated beam that first hits the central plane on a crossing line between the interface and the central plane such that the first collimated beam exits the light angle deflector along a second path substantially parallel to the longitudinal direction and is received by the second fiber. Light from the second fiber exits the second collimator along the second path into a second collimated beam that exits the light angle deflector along a third path and is received by the third fiber.

摘要： This invention discloses an optical circulator. The optical circulator includes a first set of optical components having a birefringent crystal, a pair of half wave plates and the Faraday rotator to separate and then polarize the light beam into projection-direction ready polarization components. These projection-direction ready polarization components are suitable for entering into a projection-direction optical-processing-optical device, e.g., a Wollaston prism, to generate the projecting-to-exit-port beam components. The circulator then employs a set of reciprocal components of the first set of optical components to carry out reciprocal polarization rotations and beam component merging processes to transmit an output beam to the exit port by projecting the beam components and the merged beam along the projecting-to-exit port direction.
