In the work, we have studied the PhC fiber dispersion characteristics by means of the FDTD technique. The method has been accelerated using CUDA-compatible GPU cards and its stability was compared with classical CPU computing. In contrast to other numerical methods, the FDTD allows studying the beam propagation along the fiber taking into account material dispersion and the nonlinearity. To improve...
In the paper, we investigate dynamic properties of the wideband optical filter on the basis of nonlinear photonic crystal. An all-optical flip-flop using ultra-short pulses with duration lower than 200 fs is found in such filters and has been investigated. Switching on and switching off dynamics is considered in detail. There have been carried out studies of the stability of the PhC nonlinear filter...
In the paper, we present the theoretical investigations of the nonlinear 1D and 2D photonic crystals which possess optical power limiting effect. The parameters of the structures were found as well as radiation intensities and wavelengths the stabilization is observed at. Numerical experiments have been carried out which approved the power stabilization at the output of the structures. The structures...
