Nonlinear refractive index of fs-laser-written waveguides in fused silica.
We report on the measurement of the nonlinear refractive index of fs-laser written waveguides in fused silica by analyzing self-phase modulation of the propagating light. The nonlinear index is reduced considerably compared to the bulk material by the writing process and is furthermore highly dependant on processing parameters.
