Abstract
We investigate the mechanisms of formation of long-period gratings written in a pure-silica-core fibre by using arc discharges. We show by simulation of transmission spectra of the gratings that their formation can be accounted for by the microdeformations induced in this fibre due to temperature gradients in the arc discharge. The measurement of the near-field intensity distribution confirms the asymmetry of the perturbation.
