Abstract

Filamentation of femtosecond laser pulses and self-writtten filament-induced waveguides were first among chalcogenide glassy semiconductors observed in glassy arsenic-germanium-sulfide. Recovery of refraction index profile of the self-written waveguide was carried out by solving transport of intensity equation and Abel inversion, using its ordinary microscopic images taken at different defocusing.
