Nanoscale GaP strips based photonic crystal fiber with high nonlinearity and high numerical aperture for laser applications

A novel design of circular hybrid photonic crystal fiber (CH-PCF) with highly nonlinearity and high numerical aperture (NA) is introduced in this paper. The numerical simulation results are obtained by employing the finite element method (FEM) and selecting finer mesh. The investigated parameters ar...
