Abstract

We analytically investigate the formation of the Kuznetsov-Ma breather, the Akhmediev breather and the Peregrine breather in one-dimensional exciton-polariton condensates under homogeneous pumping. We show that the breather polariton solitons obtained in this study present deformations which are completely controlled by the physical parameters of the system. The maximal intensity of these breathers is controlled by the strength of the interaction amongst polaritons. In addition, we observe that the maximal population of polaritons is obtained at the highest concentration of breathers during the condensation.
