Paper Abstract

Spectral dependencies of the optical properties of Ge-As-S films were obtained from the transmission spectra by modified Swanepoel method. The results for optical parameters were analyzed using single oscillator model. Film thickness, d, optical band gap, Egopt, oscillator energy E0, and dispersion energy, Ed, before and after exposure to light were determined. Non-linear optical properties were estimated by means of generalized Miller's rule and classical anharmonic oscillator model.
