TL;DR: In this paper, a direct, point-by-point inscription of fibre Bragg gratings by infrared femtosecond laser is reported for the first time, in a non-photosensitised, standard telecommunication fibre and dispersion shifted fibre.

TL;DR: In this article, the authors discuss the challenges facing researchers using femtosecond laser direct-write technique with specific emphasis being placed on the suitability of fused silica and phosphate glass as device hosts for different applications.

TL;DR: In this article, the authors reported the inscription of a fourth-order fiber Bragg grating made line-by-line in the optical fiber using a femtosecond laser.

TL;DR: In this article, a series of symmetric and asymmetric LPGs were inscribed in photonic crystal fiber by a low repetition rate femtosecond laser system, and they were found to be spectrally sensitive to bend orientation, with some attenuation bands producing both red and blue wavelength shifts, whilst the symmetric devices produced only a unidirectional wavelength shift.

TL;DR: In this paper, a direction-sensitive bend sensor in standard singlemode fiber is demonstrated for the first time based on an axially offset fibre Bragg grating, directly written by an infrared femtosecond laser.
