Abstract

Aberrated femtosecond laser pulses were applied to telecommunication fiber, forming long and uniform filament arrays with narrow Bragg resonances. Overlaid gratings with rotational and positional offsets enabled photoelastic bending responses for azimuthally resolved displacement sensing.
