Abstract

Amorphous chalcogenide glasses are highly transparent in the near $1{\mu}m$ wavelength region, which corresponds to the wavelength region of the optical communication system. Optical properties of these materials, including the transmittance, the optical gap, and the shift associated with reversible photostruction change, were measured. Thereafter, optical waveguide was fabricated by the laser lithographic technique and then, guide modes were measured by utilizing the end-fire coupling technique. The field patterns of both the single mode and the multimode waveguide were observed.
