    The interaction of light with matter can be engineered by controlling the photonic density of states (PDOS). I will discuss our recent work on optical topological transition in strongly anisotropic metamaterials that can be used to engineer the PDOS [1]. The transition in the topology of the iso-frequency surface from a closed ellipsoid to an open hyperboloid manifests itself in increased rates of spontaneous emission of emitters positioned in the near-field of the metamaterial.

    Following this, I will talk about our work on strongly coupled organic-inorganic hybrid excitons using microcavities. The prospects for realizing enhanced nonlinear optical response from such hybrid systems will also be discussed. Time permitting; I will discuss our work on metal nanocomposite based photonic crystals for enhancing the nonlinear optical response [2].
