Dispersive wave generation by femtosecond laser pulses in few-mode microstructure optical fiber

摘要

The decomposition of the beam on a set of orthogonal Laguerre-Gaussian functions is applied for modeling pulse dynamics in few-mode microstructure fiber. In the scalar approach the nonlinear propagation of femtosecond pulses in the anomalous dispersion 'region of microstructure fiber investigated. The simulation demonstrates the generation of dispersive waves in high-order waveguide modes.
