Abstract: Fiber Bragg gratings of low reflectivity are given a squared reflectivity function in the form of a tophat configuration having a flat top and lacking undesirable side lobes (12). Such a reflectivity function for a fiber Bragg grating is achieved by interfering a diffracted beam (20) with a plane wavefront beam so as to impose a sinc function on the resulting interference pattern that imprints the grating on an optical fiber (10).

Abstract: Overclad fiber optic couplers are made by inserting the uncoated portions of a plurality of optical fibers into the bore (14) of a glass tube, collapsing the tube midregion (15) onto the fibers and stretching the central portion of the tube midregion. The present method utilizes a glass tube (10) the bore of which includes a circular portion and a recess. A plurality of optical fibers (21, 22) are sequentially inserted into the tube by threading the coated end into the circular bore portion until the uncoated portion of fiber (23, 24) is centered in the tube. The uncoated portion of fiber is then transferred laterally into the bore (14) recess. After all fibers have been threaded into the circular bore portion and transferred to the recess, a filler fiber (28) is inserted into the circular bore portion. The resultant coupler exhibits low excess loss.

Abstract: A fiber optic coupler (51) is automatically manufactured under the control of a programmable controller (79). A fiber feed device (26) sends fibers (16-17) through a tube (50). Fibers (16-17) are stored in the tube (50). Chucks (57-58) pull in opposite directions to form a tapered coupling region. Epoxy dispensers dispense epoxy into uncollapsed ends of the coupling tube (12) bore. A UV light sources (70) cures the epoxy. The control of the apparatus by programmable controller eliminates operator inconsistencies and improves process reproducibility.

Abstract: Oscillation/rotation patterns for improving the off axis homogeneity of fused silica boules are provided. The patterns reduce the optical effects of periodic off-axis striae by decreasing the ratio of DELTA nstriae to DELTA zstriae, where DELTA nstriae is the average peak-to-valley magnitude of the striae and DELTA zstriae is their average peak-to-peak period. The oscillation/rotation patterns have long repeat periods and cause soot-producing burners to trace out substantially spiral-shaped patterns on the surface of the boule.
