Abstract

Presented here is a report on laser-excited photoluminescence data obtained in a waveguide geometry from sol-gel-derived germania-silica films whose photosensitive response was previously examined. Through a hydrogen-containing atmosphere, several samples were heat treated for different time periods to induce varied degrees of oxygen-deficiency and hydrogen-center concentrations in the films.
