Abstract

Near-zero-index (NZI) media offers fascinating properties in engineering light-matter interactions. However, the realization of integrated photonics NZI technologies relies on photonic crystals suffering from spatial dispersion and radiative losses. Our work discusses the radiative properties of Dirac-cone metamaterials, considering both the design challenges and the opportunities arising from it. In general, we discuss how designing radiative losses empowers novel forms of dissipation engineering. It allows for a pure silicon photonics implementation of generalized coherent perfect absorption (CPA) effects in classical and quantum photonic networks.
