Paper Abstract

Focused femtosecond laser pulse inside the bulk transparent materials leads to filamentary propagation. The optical intensity in the filamentary volume can become high enough to induce permanent structural modifications. The induction of filamentary structural modifications is a versatile technique for the fabrication of three-dimensional photonic devices in transparent materials. In this paper, we present applications of filamentation in microprocessing by demonstrating the fabrication of waveguide devices and diffractive optical elements in transparent materials. Filamentation is applied to micro welding of transparent substrates.
