Thermal properties of fiber Bragg gratings inscribed point-by-point by an infrared femtosecond laser
Direct, point-by-point inscription of fiber Bragg gratings by infrared femtosecond laser had been recently reported. Response of these gratings to annealing at temperatures in range 500C to 1050C is studied for the first time. Gratings inscribed by infrared femtosecond lasers were thermally stable at temperatures up to 900C, representing a significant improvement in comparison with the “common”...
متن کاملInscription of fiber Bragg gratings by ultraviolet femtosecond radiation.
We report on what is to our knowledge the first fabrication of fiber Bragg gratings by UV femtosecond radiation. The Bragg gratings, with photoinduced refractive-index modulation up to 1.92 x 10(-3) in H2-loaded SMF-28 and up to 1.05 x 10(-3) in Nufern GF1 fibers, were written by high-intensity (31-77-GW/cm2) femtosecond pulses at 264 nm. The dependence of the refractive-index modulation on int...
متن کاملPoint-by-Point Femtosecond Laser Inscription of Bragg Gratings In High NA (>0.4) Germania-Doped Optical Fibre
Using point-by-point femtosecond laser inscription, a fibre Bragg grating (FBG) was written in a high NA germania-doped fibre. Thermal tests demonstrated that the FBG could withstand temperatures up to 800°C without significant effects on reflectivity.

متن کاملTwo Beam Interferometric Inscription of UV femtosecond Fiber Bragg Gratings
The inscription of fiber Bragg gratings with femtosecond laser radiation gives access to a wide range of new materials beyond conventional UV-photosensitive and special hydrogen loaded materials. We have therefore investigated the use of an interferometric technique in combination with UV femtosecond laser pulses to generate fiber Bragg gratings in different types of fibers. Additionally, the t...
متن کاملOptical loss mechanisms in femtosecond laser-written point-by-point fibre Bragg gratings.
Fibre Bragg gratings inscribed with the point-by-point method using a Ti-sapphire femtosecond laser operating at 800 nm are shown to display strong increasing attenuation towards shorter wavelengths with a large and spectrally sharp recovery observed below 400 nm. The origin of this loss is shown to be Mie scattering, and the sharp recovery in the transmission results from wavelength dependent ...
