Abstract

To date a lot of work¹ has been carried out to understand the mechanism of second order nonlinearity in glass materials, but it has not been fully elucidated yet. Myers et al., who first reported² a permanent second order nonlinearity of a poled bulk fused silica glass, explained the origin³ by a simple ionic charge transport model in combination with bond reorientation. Our group demonstrated phase-matched second harmonic generation (SHG) in corona-poled glass film waveguides^4,5. The waveguide structure is essential for the further applications in integrated optics. Nevertheless the study on the quadratic nonlinearity in glass waveguides has not attracted much attention. In this article studies on the second order nonlinearity in corona-poled Coming 7059 glass film waveguides are reported.
