Increasing absorption bistability is studied under realistic conditions with a many-body approach for nonlinear optical absorption in semiconductor quantum wells, combining Coulomb and band structure engineering effects. ...

We study the dynamics of a vertical-cavity surface-emitting laser (VCSEL) with continuous-wave (cw) orthogonal optical injection from a tunable laser. We use the dynamical properties of polarization bistability and the ...

Stationary two-dimensional localized structures have been observed in a wide variety of dissipative systems. The existence, stability properties, dynamical evolution, and bifurcation diagram of an azimuthal symmetry breaking, ...

We study polarization switching and hysteresis in a vertical-cavity surface-emitting laser (VCSEL) subject to an orthogonal optical injection, such that the polarization of the injected light is perpendicular to that of ...

The aim of this work is to study the electromagnetically induced transparency (EIT) and the coherent population trapping (CPT) phenomena in three-level systems, such as atoms and quantum dot molecules (QDM). The present ...
