Phase-matched blue second harmonic generation was observed in a corona-poled Corning 7059 glass film waveguide. The induced quadratic optical nonlinearity was examined by second harmonic generation with a time dependent decay for multi-complex of SiO2,BaO,B2O3 and/or Al2O3. Glass films with every possible combination of composition were fabricated and examined. The glass composition of SiO2-BaO-B2O3 and/or SiO2-BaO-Al2O3 was found to play effective roles in maintaining the induced second order nonlinearity for a longer period of time. This is supposed to be related to distributed traps which come from complex of the glass components.
