Abstract
In this article, we present a new approach to study the nonlinear wave propagation along fibers having any arbitrary refractive index profile. Our algorithm devised in a finite difference platform, yields the dispersion properties precisely as applied to the representative cases. We show, by varying applied peak power, the zero dispersion wavelength (ZDW) can be shifted towards 1550 nm wavelength window. Furthermore, we establish the design of realising a flattened total dispersion profile around the Zero Dispersion Wavelength (ZDW). We have achieved consistent total dispersion values within the range of ±1.50 ps/km-nm by utilizing various core radii and highest applied powers of 28 mW, 55 mW, and 118 mW. These dispersion values remain constant over bandwidths of 223 nm, 458 nm, and 531 nm, respectively. These are new results in the context of controlling dispersion characteristics dynamically with varying applied power in the nonlinear fiber medium having any symmetric or asymmetric core cross-section.
期刊介绍:
The IEEE Journal of Quantum Electronics is dedicated to the publication of manuscripts reporting novel experimental or theoretical results in the broad field of the science and technology of quantum electronics. The Journal comprises original contributions, both regular papers and letters, describing significant advances in the understanding of quantum electronics phenomena or the demonstration of new devices, systems, or applications. Manuscripts reporting new developments in systems and applications must emphasize quantum electronics principles or devices. The scope of JQE encompasses the generation, propagation, detection, and application of coherent electromagnetic radiation having wavelengths below one millimeter (i.e., in the submillimeter, infrared, visible, ultraviolet, etc., regions). Whether the focus of a manuscript is a quantum-electronic device or phenomenon, the critical factor in the editorial review of a manuscript is the potential impact of the results presented on continuing research in the field or on advancing the technological base of quantum electronics.
