Optical devices based on registration directly in the glass su00eclica using laser pulse femtossegundos

摘要

"Optical devices based on registration directly in the glass su00eclica using laser pulse femtossegundos".The invention relates to methods of entry of a structure of light guide on a glass substrate in mass.The glass substrate in mass is preferably made of a material based on silica with a soft annealing is smaller than approximately 1380 198 k pulsed laser beam is focused inside aThe substrate while the focus is moved in relation to the substrate along the scanned path.In an effective scanning speed to induce an increase in the refractive index of the material along the scanned path.The laser does not induce substantial physical damage to the material along the scanned path. Various optical devices may be made using this method.
