The photonic density of states (PDOS), like its electronic counterpart, is one of the key physical quantities governing a variety of phenomena and hence PDOS manipulation is the route to new photonic devices. The PDOS is conventionally altered by exploiting the resonance within a device such as a microcavity or a bandgap structure like a photonic crystal. Here we show that nanostructured metamaterials with hyperbolic dispersion can dramatically enhance the photonic density of states paving the way for metamaterial-based PDOS engineering.

Quantum nanophotonics using hyperbolic metamaterials (2012, methodology): “The variation of emission intensity with time can be obtained as I(t) = ∑ 0<d<D I(d) exp(−Γ(d)t) where I(d) is the reflected intensity in the far field due to a dipole placed a distance d away from the substrate and Γ(d) is its lifetime [25].”
Hyperbolic Metamaterials (2015, background): “Since its theoretical prediction in [6], the broadband Purcell effect has been indeed observed in multiple experiments, such as [7,8].”
Plasmonic materials for energy: From physics to applications (2013, background): “-field optical coupling between SPP waves formed on each surface or wire results in formation of multiple SPP branches in the dispersion characteristics of such anisotropic metamaterials (Fig. 1(c2)) [48, 49, 50, 51, 52]. In the limit of the infinite number of ultra-thin layers, such metamaterials c”
Low-loss, infrared and terahertz nanophotonics using surface phonon polaritons (2015, background): “The potential for hyperbolic media has been extensively discussed in the literature [80, 177, 178], however it has focused primarily on plasmonic/dielectric stacked systems, which typically exhibit high plasmonic losses and only support negative Re(ε) along one principal axis.”
