## Abstract The numerical solution of a wave equation describing the propagation of the laser pulse of a few optical cycles in fused silica is obtained. Our numerical simulations closely follow the published experimental data. A shifting of the spectrum peak of the broadened pulse, depending on the
1-to-8 and 1-to-4 optical waveguide power splitters were fabricated using the focused 800 nm-amplified femtosecond laser to directly write a series of 1-to-2 Y-junction splitters in a fused silica glass sample. A shifted multi-scan technique was developed to substantially reduce the excessive insert
