- 論文の詳細を見る
We have extended the finite-difference time-domain (FDTD) solution of Maxwell's equations to nonlinear propagation in a silica fiber. The combination of linear polarization, including all exact Sellmeier-fitting values, and nonlinear polarization, involving the Raman response function, in the FDTD method is novel. We have compared the extended FDTD method with the previous solution of the generalized nonlinear Sehrodinger equation by the split-step Fourier method with a slowly varying-envelope approximation, and experimental results. To the best of our knowledge, this is the first comparison between FDTD calculation and experimental results for ultrashort (12 fs) laser propagation in a silica fiber.
