Abstract

Refractive index changes in a-SiO₂ consist of positive index variations or regular nanoscale patterns. We spectroscopically reveal the electronic and structural transformation of glass in the self-organized structures, indicating bond breaking and oxygen deficiency. We equally propose a method of real time control of nanogratings formation under the action of ultra -short laser pulse with variable envelopes. Application as polarizing optical devices is discussed.
