Abstract
We show that broad-area cascade lasers with no absorbing intracavity elemen ts support the spontaneous formation of two-dimensional bright localized st ructures in a dark background. These cavity solitons consist of islands of two-photon emission embedded in a background of single-photon emission. We discuss the mechanisms through which these structures are formed and intera ct, along with their properties and stability.
