Modeling photonic crystal fiber for efficient soliton pulse propagation at 850 nm

We numerically investigate the dynamics of soliton propagation at 850 nm in chloroform filled liquid core photonic crystal fiber (LCPCF) by using both finite element method (FEM) and split step Fourier method (SSFM) We propose a novel chloroform filled PCF structure that operates as a single mode at 850 rim featuring an enhanced dispersion and nonlinearity for efficient soliton propagation with low input pulse energy and low loss over small distances We adopt the projection operator method (POM) to derive the pulse parameter equations which clearly describes the Impact of fourth order dispersion on the pulse propagation in the proposed PCF To analyse the quality of the pulse we perform the stability analysis of pulse propagation numerically and compare our results of the newly designed chloroform filled PCF with that of standard silica PCF From the stability analysis we infer that the soliton pulse propagation in modified chloroform filled PCF is highly stable against the perturbation (C) 2010 Elsevier BV All rights reserved
