The apparatus includes a first beam bender. 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 birefringent crystal is oriented such that and has a thickness between its first and second faces selected such that a first component of the optical beam having a first polarization exits the crystal at its second face and enters the end of the second optical fiber along the second optical axis and a second component of the optical beam having a second polarization orthogonal to the polarization of the first polarization exits the crystal at its second face and enters the end of the third optical fiber along the third optical axis.

    摘要: Optical devices are disclosed, one example of which includes first and second polarization maintaining (“PM”) fibers. The first and second PM fibers in this example are disposed beside each other to form a grouping that includes a secondary axis defined by the first and second PM fibers. The first and second PM fibers are oriented such that a fast axis of the first PM fiber is non-parallel with respect to a fast axis of the second PM fiber. Finally, the optical device is configured so that each of the PM fibers maintains a distinct optical transmission path.

    摘要: 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.
