Paper Abstract

Second harmonic generation was obtained with an interesting efficiency in thermally poled sulfide glass. The best results obtained to date for chalcogenide glasses were on a Ge-Sb-S system thanks to an adapted treatment of thermal poling. The poling parameters like temperature (100-310 °C), applied voltage (2.5-4 kV)and duration (5-60min) were explored. A large NL second-order susceptibility χ(2) of about 10 ± 0.5 pm/V was measured. The nonlinear susceptibility profile as a function of the depth under the anode for Ge25Sb10S65 poled glass was determined using the analyze of remained second harmonic signal during the NaOH etching treatment. In parallel, a study of the concentration variation of elements being able to be involved in the formation of a charge space was achieved by using the secondary ion mass spectroscopy.
