Study of the propagation of solitary waves produced by an assembly of quantum dots through optical fibers

Abstract

Abstract In this research, the potential use of semiconductor nanostructures as optical field sources to optimize the propagation of lossless pulses along non-linear optical fibers is studied. During this investigation, we propose the external excitation of a set of semiconductor SQD points through a source of optical pulses, giving rise to the generation of solitonic pulses that propagate through an optical fiber with non-linear optical characteristics. Theoretically, soliton formation studied from the non-linear interaction between SQD and external optical excitation. In the study, the non-linear Schrödinger NLSE equation solved numerically using the Fourier Split-Step method to understand the evolution of the soliton emitted for SQD within an optical fiber with real physical parameters.
