The spontaneous emission of photons from atomic ensembles initially excited have been shown to exibit interesting cooperative behaviors such as increased emission rate (superradiance) or spatial directionnality [1]. This process is today connected to experimental challenges aiming for example to develop quantum memories, single photons sources or quantum repeaters [2],[3].

After a brief review of this context, we will show in this talk spatial emission patterns from choosen atomic ensembles, obtained numerically. Motivated by the volunty to give comprehensive pictures, we will consider samples from 2 to thousands of atoms and study the case of realistic experimental preparation.
