Abstract

Aberrated femtosecond laser pulses were applied to telecommunication fiber to open nano-filament arrays through the silica cladding and waveguide cross-section. Strong photonic bandgap response from n-shifted, second-order Bragg gratings enabled high resolution refractive index sensing. ©2020 The Author(s)
