  • Methods and apparatusses for packaging long-period fiber gratings
    Patent number: 6301410
    Abstract: Packages for long period fiber gratings and other optical components (and methods for forming the packages) are described. According to an aspect of the invention, a hollow tube surrounding an optical fiber containing a long-period grating is collapsed in two areas, forming a seal at each end of the tube. According to another aspect of the invention, a hollow tube with a shelf section at each end surrounds an optical fiber containing a long-period grating. The hollow tube is sealed at each end with a fused frit. According to another aspect of the invention, a hollow tube surrounding an optical fiber containing a long-period grating is sealed at each end with a glass plug.

  • Infra-red detector
    Patent number: 4786335
    Abstract: A novel multilayer photoconductive I.R. detector is formed by incorporating alternate p and n-type layers, such that many layers occupy the detector thickness. The detector may be considered as a n-type photoconductor containing buried isolated p-type regions which give rise to internal electric fields the effect of which is to enhance minority carrier lifetime and inhibit motion of minority carriers towards surfaces.
