Abstract: The photonic density of states PDOS, like its- electronic coun- terpart, isone of the key physical quantities governing a variety of phenom- ena and hencePDOS manipulation is the route to new photonic devices. The PDOS isconventionally altered by exploiting the resonance within a device such as amicrocavity or a bandgap structure like a photonic crystal. Here we show thatnanostructured metamaterials with hyperbolic dispersion can dramaticallyenhance the photonic density of states paving the way for metamaterial basedPDOS engineering.
