  • Tunable dispersion compensator for an optical transmission system
    Patent number: 7171079
    Abstract: Provided is a tunable dispersion compensator based on an optical fiber grating for use in an optical transmission system. A tunable dispersion compensator comprises: a disk; a ring surrounding the disk, wherein the ring is rotatable independent of the disk; and a bendable plate crossing the disk and having end parts configured to move with the rotation of the ring, wherein at least one of the optical fiber grating is attached to the plate.
    Type: Grant

    Date of Patent: January 30, 2007
    Assignee: Korea Institute of Science and Technology
    Inventors: Jun-Kye Bae, Jun-Hee Kim, Young-Geun Han, Sang-Hyuck Kim, Sang-Bae Lee
  • Tunable dispersion compensator for optical communication system
    Patent number: 7003199
    Abstract: The present invention relates to a tunable distribution compensator, including: an optical fiber having a chirped optical fiber grating; first and second frames having first and second stepped portions, respectively, wherein the first stepped portion is symmetrically faced to the second stepped portion; a first metal plate with a predetermined length for attaching the optical fiber; a second metal plate seated on the first and second stepped portions; and a bending unit connected to the first and second frames and the second metal plate for symmetrically bending the optical fiber.

  • Arbitrary filter shape tuning methods of long-period fiber gratings based on divided coil heater
    Publication number: 20040086227
    Abstract: Disclosed is an optical fiber grating comprising: optic fiber having periodically formed gratings; and a temperature control method for independently controlling temperature along grating sections. In the optical fiber, the temperature is controlled along grating sections, the desired spectrum can be obtained by varying the refractive index of each unit section, and the fiber gratings can be applied to various optical communication devices.
