  • Publication number: 20030142923
    Abstract: An improved linear polarization maintaining fiberoptic array and a method of making the array are disclosed. The fibers of the array are seated in V-grooves formed in two silicon plates, which are then approximated and bonded together to hold the fibers securely therebetween. The terminal portions of the fibers are disposed in alumina, glass or zirconium ferrules, which protect the fibers from distortion and degradation of their extinction ratios, caused by asymmetric external pressure of the housing. Using the method of manufacture disclosed herein, it is possible to test each fiber prior to its incorporation in the array.

  • Publication number: 20030123061
    Abstract: A technique for dynamic optical alignment precisely adjusts the relative position of a first linear arrangement with respect to a second linear arrangement by correcting rotational misalignment about the vertical axis, establishing an optimal displacement therebetween along an optical axis, correcting rotational misalignment about the optical axis, and setting an optimum displacement therebetween on the vertical axis. The technique is carried out semiautomatically using a computer to operate actuators to control movement of the first linear arrangement, while the second linear arrangement is fixedly disposed on a substrate. When optimal alignment has been established, the first linear arrangement is fixedly attached to the substrate.
