<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 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 کاملOptically switched erbium fibre laser using a tunable fibre-Bragg grating
The ability to tune the Bragg wavelength of a fibre-Bragg grating (FBG) in an all-fibre laser can offer added functionality such as laser wavelength tunability, polarization selectivity, and Q-switching. Compared to current techniques which rely on mechanically straining the FBG to achieve Bragg-wavelength tunability, an all-optical technique for tuning an FBG offers potentially faster switchin...
متن کاملAll-optical, actively Q-switched fiber laser.
All-fiber lasers offer increased robustness and simplicity over other fiber laser systems. Current active Q-switching techniques for all-fiber lasers rely on electro-mechanical transducers to strain-tune an intra-cavity fiber-Bragg grating, which adds complexity and can lead to vibrational sensitivity. An all-optical technique for achieving active Q-switched operation is a more elegant approach...
متن کاملCompact, all fibre, linearly polarised, single-mode Ytterbium doped fibre laser utilizing point-by-point inscribed intra-core fibre Bragg gratings
We report on the development of a compact, all fibre laser source operating at 1 μm with a linearly polarized (extinction ratio > 20 dB) and very narrow linewidth (12 pm) output. The unique cavity design included a fibre Bragg grating high reflector and output coupler, inscribed via the point-by-point method directly into the active core. A single splice within the cavity between the fibre inco...
