The Effect of Hydrogen Diffusion in the Transmission Spectrum of LPGs Fabricated Using Hydrogen Loaded SMF-28 Fiber
نویسندگان
چکیده
The effect of hydrogen diffusion on the transmission spectrum of Long Period Grating (LPG) is investigated by monitoring the wavelength shift and the intensity variation in the loss peaks. The LPG is inscribed in a hydrogen loaded standard telecommunication fiber and experiments are performed at different annealing temperature and time to observe the spectral changes. Keywords— Fiber grating, Long Period Grating, photo sensitivity, annealing, hydrogen diffusion.

Dynamic evolution of the spectrum of long-period fiber Bragg gratings fabricated from hydrogen-loaded optical fiber by ultraviolet laser irradiation.
Long-period fiber Bragg gratings fabricated by exposure of hydrogen-loaded fiber to UV laser light exhibit large-scale dynamic evolution for approximately two weeks at room temperature. During this time two distinct features show up in their spectrum: a large upswing in wavelength and a substantial deepening of the transmission minimum. The dynamic evolution of the transmission spectrum is expl...
متن کاملCavity-enhanced spectroscopy in optical fibers.
Cavity-enhanced methods have been extended to fiber optics by use of fiber Bragg gratings (FBGs) as reflectors. High-finesse fiber cavities were fabricated from FBGs made in both germanium/boron-co-doped photosensitive fiber and hydrogen-loaded Corning SMF-28 fiber. Optical losses in these cavities were determined from the measured Fabry-Perot transmission spectra and cavity ring-down spectrosc...
