Optically Injected And Mutually Coupled Frequency Distinct Semiconductor Lasers, Beatriz Baselga-Pascual

Theses

In the following work we examine the dynamics of semiconductor lasers under different types of coupled oscillator configurations, namely optical injection and mutual coupling. We examine both discrete-mode quantum well lasers and distribute feedback quantum dot lasers. First we describe optical injection experiments carried out on single mode semiconductor lasers. Conventional diagnostic tools such as optical spectra, RF spectra and intensity time series are used to describe the dynamics. We also describe a novel interferometric technique used to experimentally resolve the phase of the slave laser. This new technique has proved successful, revealing some heretofore hidden dynamical features and showing …
