Their unique proprieties (multistability, plasticity, etc) make CSs in VCSELs excellent candidates optical “bits” for applications to information storage and processing : Parallel and reconfigurable optical memories, all-optical logic gates and circuits, optical delay lines, serial to parallel converters.
The CSs sensitivity to gradients of the cavity detuning induced by device defects allows to conceive "soliton force" microscopes inhomogeneities.
Note: Recent theoretical results obtained in a prototypical 2-level atom resonator show three dimensional light self-localization in form of cavity light bullets (CLBs) .
Our main research activities focus on the theoretical study of self-confinement in two (CSs) and three spatial dimensions (CLBs) in semiconductor lasers.
In particular we collaborate at the theoretical prediction of the existence and manipulability of cavity solitons in VCSEL  and of cavity light bullets in a prototypical nonlinear resonator .
In the framework of the national project ”Futuro in Ricerca” FIRB-grant PHOCOS we recently started to investigate the generation and control of CSs in a hybrid conservative and dissipative system consisting of a centrosymmetric photorefractive crystal in contact with a broad area VCSEL.
