In this paper, the accurate and numerically efficient finite element (FE)-based beam propagation method (BPM) has been employed to investigate second harmonic generation (SHG) in highly nonlinear soft glass (SF57) equiangular spiral photonic crystal fibers (ES-PCFs) for the first time. It is shown here that the SHG output power in highly nonlinear SF57 soft glass PCF exploiting the ES design is significantly...
Design and analysis of various photonic crystal fibers are reported, particularly for their single-mode single-polarization operation, dispersion control and nonlinear applications by using full-vectorial finite element simulations.
