Abstract

Summary from only given. Amorphous chalcogenide glass (ChG) films are candidates for all-optical integrated circuits for the telecommunication industry due to their excellent infrared transparency, large nonlinear refractive index, and low phonon energies. This paper describes for the first time to our knowledge, material ablation and corresponding structural changes in single and multilayer ChG thin films, using an unamplified Ti:sapphire laser.
