    摘要： A fiber optic polarization maintaining apparatus for use in fabrication of fused optical couplers, where the fused optical couplers include first and second optical fibers which each have a principle axis. A light launching source is coupled through a lens into a first end of a selected one of the first and second optical fibers. A piezoelectric element in combination with a solenoid applies external stress in the form of an AC modulation signal to the selected one of the first and second optical fibers. A rotating apparatus rotates the selected one of the first and second optical fibers during modulation. Apparatus for collimating light is coupled to a second end of the selected fiber. Apparatus for analyzing the collimated light is coupled to the collumating apparatus, apparatus for detecting power is coupled to the analyzing means, and an output of the power detecting apparatus is coupled to an apparatus for determining when the principle axis of the selected fiber is aligned in the direction of the externally applied stress by detecting a null output from the power detecting apparatus.

    摘要： This invention relates to a method of drawing twist-free optical fibers; it is particularly useful for drawing polarization retaining single-mode optical fibers having azimuthal inhomogeneities. There is applied to the fiber, during the drawing thereof, a coating having a non-circular cross-section, the azimuthal inhomogeneity of the fiber being positioned in a substantially constant orientation with respect to the non-circular cross-section of the coating. In another embodiment, a plurality of fibers having azimuthal inhomogeneities are drawn from a plurality of preforms that are properly oriented in the draw furnace. The fibers are drawn through the same coater so that the azimuthal inhomogeneity of each fiber is oriented in a substantially constant relationship with respect to the azimuthal inhomogeneities of the remaining fibers in the coating.

    摘要： A fiber laser sensor is comprised of two fiber lasers which are each optically coupled to a third fiber so that energy is exchanged between each of the laser fibers and the third fiber. The coupling is accomplished by arranging the laser fibers parallel to and on either side of a third fiber and properly spacing the three fibers to produce optical coupling along the length of the fibers. The central fiber ends are non-reflective so that light generated by one of the lasers and coupled to the central fiber is lost except for a small fraction of the energy transferred to the other laser. Accordingly, the structure operates with the least loss when the two lasers oscillate at a common frequency but 180.degree. out-of-phase. The resonant cavities of the two fiber lasers are made non-identical by making the path length one cavity slightly longer than the other to produce Vernier tuning of the laser resonant frequency orders relative to each other with only one common resonant frequency. The device can be used as a sensor because the common laser output frequency is sensitive to changes in the optical path length of either or both of the laser cavities.

    摘要翻译： 光纤激光传感器包括两个光纤激光器，每个光纤激光器光学耦合到第三光纤，使得能量在每个激光光纤和第三光纤之间交换。 耦合是通过将激光光纤平行于第三光纤的任一侧布置并且适当地间隔三根光纤以沿着光纤的长度产生光学耦合而实现的。 中心纤维端部是非反射性的，使得由激光器之一产生的光和耦合到中心光纤的光损失，除了转移到另一激光器的能量的一小部分之外。 因此，当两个激光器在共同频率振荡但是180°异相振荡时，该结构以最小的损耗运行。 两个光纤激光器的谐振腔通过使路径长度一个空腔比另一个稍长，使得激光谐振频率相对于彼此具有仅一个共同谐振频率的微调调谐而使得不相同。 该器件可以用作传感器，因为常见的激光输出频率对于激光腔中的一个或两个的光路长度的变化敏感。

    摘要： Systems and methods for a resonant fiber optic gyroscope with a polarizing crystal waveguide coupler are provided. In one embodiment, an optical fiber resonator comprises: a polarizing single crystal material having a first crystal lattice axis; a first waveguide formed in the crystal material; a second waveguide formed in the crystal material running parallel to the first waveguide; and an optical fiber sensing coil. The first waveguide comprises a bend that approaches the second waveguide defining a coupling region between the first and second waveguides. The first and second waveguides are polarized to guide light having a polarization state aligned to the first crystal lattice axis. The second waveguide and the sensing coil are coupled into a resonator configuration forming a ring resonator, the second waveguide comprising a first port coupled to a first end of the coil, and a second port coupled to a second end of the coil.
