Femtosecond Laser Modification of Silica Optical Waveguides for Potential Bragg Gratings Sensing

Femtosecond Laser Modification of Silica Optical Waveguides for Potential Bragg Gratings Sensing

The optimum femtosecond laser direct writing of Bragg gratings on silica optical waveguides has been investigated. The silica waveguide has a 6.5 × 6.5 µm<sup>2</sup> cross-sectional profile with a 20-µm-thick silicon dioxide cladding layer. Compared with conventional grating inscribed o...
