Numerical Simulations on Nonlinear Dynamics in Lasers as Related High Energy Physics Phenomena

Abstract

This paper aims to present some results on nonlinear dynamics in active nanostructures as lasers with quantum wells and erbium doped laser systems using mathematical models, methods, and numerical simulations for some related high energy physics phenomena. We discuss nonlinear dynamics of laser with quantum wells and of fiber optics laser and soliton interactions. The results presented have important implications in particle detection and postdetection processing of information as well as in soliton generation and amplification or in the case that these simulations are thought to be useful in the experiments concerning the high energy particles. The soliton behaviour as particle offers the possibility to use solitons for better understanding of real particles in this field. The developed numerical models concerning nonlinear dynamics in nanostructured lasers, erbium doped laser systems, the soliton interactions, and the obtained results are consistent with the existing data in the literature.

Nonlinear Dynamics in Optoelectronics Structures with Quantum Well

“…This result shows the complexity of system dynamics, without this complexity to be fully elucidated to date [12].…”

“…The corresponding bifurcation diagrams are shown in [12]. At a value of parameter m for which the dynamics is 2 T (nT), the representation consists of two points (n points).…”

“…A quantum well (QW) structure improves the functioning characteristics of laser diodes and of the solar cells as the emitted wavelength depends on nanostructure dimension (quantum size effect) [3,[10][11][12][13]. Such a structure is one in which the active region of the device is so narrow that quantum confinement occurs, according to quantum mechanics.…”
