Ion-exchange waveguides on home-made Er-Yb codoped phosphate glass and error analysis in m-lines technology

摘要

This paper addresses the fabrication of thermal ion-exchange waveguides and error analysis in m-lines technology. Planar waveguides are fabricated on home-made Er-Yb co-doped phosphate glass substrate by thermal ion-exchange method, the effect of exchange temperature, anneal time, exchange time, and molten salt composition on the refractive index profile is investigated using m-line technology and uncertainty of measurement is also given.
