Efficient simulation of unidirectional pulse propagation in high-contrast nonlinear nanowaveguides

Jonathan AndreasenMiroslav Kolesik — 2013

Nanoscale Systems: Mathematical Modeling, Theory and Applications

This work demonstrates an improved method to simulate long-distance femtosecond pulse propagation in highcontrast nanowaveguides. Different from typical beam propagation methods, the foundational tool here is capable of simulating strong spatiotemporal waveform reshaping and extreme spectral dynamics. Meanwhile, the ability to fully capture effects due to index contrast in the transverse direction is retained, without requiring a decomposition of the electric field in terms of waveguide modes. These...
