    • An apparatus for optically circulating light beams between ports is disclosed, with a first port positioned at a proximal end of the apparatus, a second port positioned at a distal end of the apparatus, and a third port positioned at the proximal end of the apparatus. The first port is capable of transmitting a first light beam and the second port is capable of transmitting a second light beam. The apparatus includes a first beam bender. The first beam bender has opposing first and second faces. The first face and the second face are at an angle to one another. The first face and the second face intersect a longitudinal axis extending from the proximal to the distal end of the optical circulator. The beam bender is responsive to a polarization orientation of the first light beam to refract the first light beam toward the second port. The beam bender is further responsive to a polarization orientation of the second light beam to refract the second light beam toward the third port. The apparatus may additionally comprise end portions and imaging elements. The first and second end portions are positioned at either end of the apparatus to impart a propagation direction dependent polarization to the first light beam and the second light beam. The first imaging element and the second imaging element are positioned between the first and second end portions. The first imaging element bends the first light beam to a focal point between the first and the second imaging element. The second imaging element bends the second light beam to the focal point. The first beam bender is positioned proximate the focal point and is responsive to a polarization orientation of the first light beam to refract the first light beam toward the second port, and is further responsive to a polarization orientation of the second light beam to refract the second light beam toward the third port.
    • 公开了一种在端口之间光学循环光束的装置,其中第一端口位于设备的近端,位于设备远端的第二端口和位于设备近端的第三端口。 第一端口能够传输第一光束,第二端口能够传输第二光束。 该装置包括第一光束弯曲机。 第一光束弯曲器具有相对的第一和第二面。 第一面和第二面彼此成角度。 第一面和第二面相交于从光循环器的近端延伸到远端的纵轴。 光束弯曲器响应于第一光束的偏振取向以将第一光束朝向第二端口折射。 光束弯曲器进一步响应于第二光束的偏振取向以将第二光束折射到第三端口。该装置还可包括端部部分和成像元件。 第一和第二端部位于装置的任一端,以赋予与第一光束和第二光束相关的传播方向依赖偏振光。 第一成像元件和第二成像元件位于第一和第二端部之间。 第一成像元件将第一光束弯曲到第一和第二成像元件之间的焦点。 第二成像元件将第二光束弯曲到焦点。 第一光束弯曲器位于焦点附近并且响应于第一光束的偏振取向以朝向第二端口折射第一光束,并且还响应于第二光束的偏振取向以折射第二光束 光束朝向第三个端口。
