| Sumario: | ABSTRACT: Semiconductor lasers are devices widely used in several applications in order to produce coherent light, due to their remarkable advantages over other kind of lasers. The so-called VCSELs, Vertical-Cavity Surface-Emitting lasers, are especially interesting because of their applications in communications. In recent years the optical injection technique has been widely studied, paying special attention to the nonlinear dynamics of the emitted light by the injected laser. This is the main subject of this Thesis. Dynamics are studied from a theoretical and experimental point view, considering the total emitted power and the power of both polarizations. After the extraction of the parameters of a VCSEL (chapters 2 and 3), we study the single orthogonal optical injection (chapters 4 and 5), the double injection for generation of microwaves (chapter 6) and two applications of the injection technique: an all-optical inverter (chapter 7) and the enhancement of chaotic bandwidths (chapter 8). |
