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 optical isolator includes a first stage configured to refract a light ray applied in a forward direction into a first ray and a second ray. A second stage rotated 90° with respect to the first is configured to refract said first and second rays in a substantially parallel manner. The isolator is configured such that the first ray comprises an e-ray with respect to the first stage and an o-ray with respect to the second stage, and the second ray comprises an o-ray with respect to the first stage and an e-ray with respect to the second stage, thereby substantially reducing the effects of polarization mode dispersion.

摘要： A collimating device having adjustable features that facilitate proper optical alignment of components positioned within the collimator is disclosed. In one embodiment, the collimating device includes a collimating portion including a collimating element, a core portion containing an optical device, and at least one adapter portion. An engagement surface on one end of the collimating portion is shaped to engage a corresponding engagement surface on one end of the adapter portion to form an adjustment point. An additional adjustment point is defined between another end of the adapter portion and an end of the core portion. These adjustment points enable the collimating portion to be maneuvered with respect to the core portion in order to align the collimating device. Minimal clearances between the adjustment point surfaces minimize the amount of adhesive needed to bond the collimator portion together after alignment, thereby producing a more stable and secure collimating device.

摘要： An improved polarization beam splitter formed by a collimator and two similarly shaped, birefringent crystal prisms is provided. The light from the collimator is incident upon the first face of the first birefringent crystal prism which also has second and third faces. The collimated light is incident upon the second face at an angle .phi. with respect to a line normal to the second face so that light polarized perpendicular to a plane of incidence upon the second face is reflected toward the third face and light polarized in the plane of incidence is refracted at the second face. The second birefringent crystal prism has a second face parallel to, and in close proximity with, the second face of the first birefringent prism so that light refracted at the second face of said first prism is refracted at the second face of the second prism and into the second prism. A first face of the second prism is positioned with respect to its second face so that light refracted into the second prism is refracted at the first face from the second prism cross-sectionally undistorted with respect to a cross-section of the light polarized in the plane of incidence at the second face of the first prism. This polarization beam splitter can handle high power without distorting the beam.
