Abstract: Optical space in metamaterials may be engineered to mimic the landscape of amultidimensional Universe which has regions of different topology and differenteffective dimensionality. The -metamaterial landscape- may include regions inwhich one or two spatial dimensions are compactified. Nonlinear optics ofmetamaterials in these regions mimics either U1 or SU2 Kaluza-Kleintheories having one or more kinds of effective charges. As a result, novel-photon blockade- nonlinear optical metamaterial devices may be realized.Topology-changing phase transitions in such metamaterials lead to considerableparticle creation perceived as flashes of light, thus providing a toy model ofbirth of an individual physical Universe.
