Field propagation study in ultra-small core photonic crystal fiber beyond the fundamental mode cut-off
Abstract We present the study of the behavior of the electromagnetic field propagating in the ultra-small core photonic crystal fiber (PCF) beyond its fundamental mode cut-off. We first the use plane waves expansion (PWE) method to find necessary parameters and then involve the finitedifference time-domain (FDTD) method accelerated with a graphic p...
Novel shaped solid-core photonic crystal fiber for the numerical study of nonlinear optical properties
Published in Optical and Quantum Electronics
A newly developed pentagonal photonic crystal fiber (P-PCF) with high nonlinearity and birefringence has been introduced in this work. Numerical analysis is carried out across the broader wavelength spectrum from 1.0 to 2.0 μm within the inferred region (IR). Furthermore, using the finite element method (FEM) with smaller mesh, a numerical examinat...
