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, E_gopt, oscillator energy E₀, and dispersion energy, E_d, 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.
