We propose and demonstrate the use of a new potassium-ion source for glass waveguide fabrication based on a KI–ZnCl2 mixture. Planar waveguide were made using glasses such as BK7, Pyrex, soda lime, and commercial semiconductor doped glasses. The optical quality of the waveguides prepared compare favorably with the quality obtained using other fabrication techniques and the processing time is considerably reduced.
