Abstract :
A simple technique for characterising nonlinear gratings for quasi-phase-matched structures is presented. The method is based on an analysis of the spectral characteristics of the second-harmonic beam generated in a pulsed regime. The potential of the technique is experimentally demonstrated using periodically poled D-shaped silica fibres, a promising second order nonlinear material
