Linear and nonlinear optical properties of co-sputtered Ge-Sb-Se amorphous thin films
Original language description
Amorphous Ge-Sb-Se thin films were co-sputtered from GeSe4 and Sb2Se3 targets. Depending on the film composition, linear optical properties were studied by ellipsometry. The Kerr coefficient and two-photon absorption coefficient were estimated using Sheik-Bahae’s formalism for co-sputtered films of GeSe4-Sb2Se3 compared to GeSe2-Sb2Se3 pseudo-binary system and As2Se3 as reference. The Kerr coefficient was found within the range of 4.9-21x10-18. Compositions being close to (GeSe4)50(Sb2Se3)50 pseudo-binary (i.e., Ge7.5Sb25.0Se67.5) provides just the trade-off between a high Kerr coefficient and low optical losses related to two-photon absorption.
