Optical self-organization and cavity solitons in optically pumped semiconductor microresonators

We study the self-organizing properties of an optically driven semiconductor microresonator especially designed and optimized for optical pumping wherein patterns and cavity solitons are observed for the first time with all-optical excitations. We demonstrate both coherent and incoherent writing and erasure of cavity solitons achievable on the same sample, enriching the spectrum of the system functionalities. Finally, we show how the system lends itself to the multiplication of the number of cavity solitons and how they possibly coexist.
