Stochastic and Nonlinear Effects in Semiconductor Lasers
Abstract
Semiconductor lasers are key elements in optical technologies, being coherent light sources in fiber optics communications, optical data storage, life sciences applications, material processing, and sensing. They have a huge economic impact and are crucial for the photonics technologies that improve our everyday life style. For developing the next generation of semiconductor lasers, more compact, faster, reliable and low-cost, is crucial to have a good understanding of the nonlinear light-matter interactions in semiconductor active media, and their nontrivial interplay with the various noise sources (such as spontaneous emission, thermal and electrical noise). Within the framework of this two-year project, detailed experimental and numerical studies have been performed, focusing on the interplay of noise and nonlinear dynamics. Specifically, we introduced a novel method of nonlinear time-series analysis, based on symbolic ordinal analysis, to characterize the temporal correlations of the intensity dropouts of a semiconductor laser with optical feedback operating in the low-frequency fluctuations regime.
