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.
我们通过分析传播光的自相位调制，报告了对熔石英中飞秒激光写入波导的非线性折射率的测量。与块状材料相比，写入过程使非线性折射率大幅降低，并且其还高度依赖于加工参数。
