Some samples exhibited refractive index reduction without any structural modification, which was brought about by local increase in fictive temperature through spot heating and quenching. With the aid of a computer simulation using a finite element method, such a modification is found to occur when the maximum surface temperature is less than 1000 degC for the Cu-doped glass."
