Point-by-Point Femtosecond Laser Inscription of Bragg Gratings In High NA (>0.4) Germania-Doped Optical Fibre
نویسندگان
چکیده
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.

<Edited by Milan Brandt and Erol Harvey> POINT BY POINT FEMTOSECOND LASER INSCRIPTION OF FIBRE AND WAVEGUIDE BRAGG GRATINGS FOR PHOTONIC DEVICE FABRICATION
We present a flexible and rapid method for the production of Bragg gratings in a range of optical waveguides such as optical fibres and direct laser-written waveguides in bulk media. Using a low repetition rate (1 kHz) femtosecond laser, Bragg grating structures can be written in a point-by-point fashion (where each laser pulse inscribes one period of the Bragg structure) in both passive and ac...
متن کاملPoint-by-point inscription of first-order fiber Bragg grating for C-band applications.
The influence of the fiber geometry on the point-by-point inscription of fiber Bragg gratings using a femtosecond laser is highlighted. Fiber Bragg gratings with high spectral quality and strong first-order Bragg resonances within the C-band are achieved by optimizing the inscription process. Large birefringence (1.2x10(-4)) and high degree of polarization-dependent index modulation are observe...
متن کاملNovel fibre laser sources based on point-by-point femtosecond laser inscribed fibre Bragg gratings
Like any other laser, a fibre laser consists of an active medium (in this case a piece of doped optical fibre) between two feedback elements. While Fresnel reflection from the fibre end facet can assume the role of a broadband partially reflecting output coupler, fibre Bragg gratings (FBGs) are an obvious choice for the implementation of a frequency selective high reflector in an all-fibre desi...
متن کاملThermal 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 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 ...
