    Nonlinear Optics and Saturation Behavior of Quantum Dot Samples Under Continuous Wave Driving

    The nonlinear optical response of self-assembled quantum dots (QD) is relevant to the application of QD-based devices in nonlinear optics, all-optical switching, slow light, and self-organization. Theoretical ...

    Cavity soliton laser based on VCSEL with saturable absorber

    We study theoretically a broad-area vertical cavity surface emitting laser (VCSEL) with a saturable absorber. We show numerically the presence of cavity solitons in the system: they exist as solitary structure...

    Model for optical pattern and cavity soliton formation in a microresonator with self-assembled semiconductor quantum dots

    We have developed a model that describes the optical response of a semiconductor quantum dot medium in a cavity in order to investigate pattern and cavity solitons formation. This model, beyond the inclusion o...

    Cavity Spatial Solitons in Semiconductor Microcavities

    In the framework of Transverse Nonlinear Optics and Optical Pattern Formation, we study the formation of cavity solitons (CS) in semiconductor microcavities. We adopt a microscopic model that describes the fie...

    Laser-Based Optical Associative Memories

    A new approach to architecture based on the use of a laser as a nonlinear discriminator for all-optical, auto- and hetero-associative memories is presented. The laser operates in a regime of spatial multistabi...

    Localized Structures In Nonlinear Optical Systems And Materials

    Diffractive effects in passive nonlinear optical resonators can lead to pattern forming bifurcations with subcritical character. When the pattern (in our case, a regular hexagonal lattice of inte...

    Instabilities and pattern formation in a Laser with Injected Signal

    In the last years, diffractive effects coupled to medium nonlinearity in nonlinear optical systems were increasingly investigated as the main means of pattern formation and spatio-temporal dynamics in optics [1].

    Quantum Noise Reduction and Instabilities in Nondegenerate Four-Wave-Mixing

    Four-wave-mixing (FWM) is one of the basic mechanisms in nonlinear optics. We consider the interaction of a pump field of frequency ω l and two signal fields (or more precisely, a signal and an id...
