Abstract

It has recently been shown that large second-order nonlinearities may be induced in optical fibres by an excitation poling technique. In this, high-intensity blue light is launched the fibre core. Two-photon absorption then gives rise to the excitation of defect centres, which align in the presence of the dc-field. The process is strongly linked to the generation of χ(2)-gratings from noise or by seeding and the formation of Hill-gratings.
