  • 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.
