We study the optical response of cold three-state atoms under conditions of electromagnetically induced transparency, where one atomic level corresponds to a Rydberg state that exhibits very strong van-der-Waals interactions. Using different numerical and analytical approaches we show that this leads to a non-linear and highly non-local optical response of the EIT medium, which, moreover, exhibits universal behavior . Good agreement with recent measurements of the nonlinear absorption in Rb-Rydberg gases is demonstrated. Furthermore, we show that the resulting non-local photon-photon interactions can give rise to interesting nonlinear wave phenomena , such as stable bright solitons and modulational instabilities.
