| Abstract: |
| The fluorescence emission enhancement through manipulation of photonic Local Density of States (LDOS) is one of the growing research interests in the nanostructure literature. In this regard, Hyperbolic Metamaterials (HMMs) play a significant role in the LDOS engineering through the concept of high-k modes. Despite theoretical predictions, it is proved that LDOS is not an infinite amount in practical HMMs and number of periods is a drastic parameter affecting LDOS of the finite thickness HMMs. In the present study, emission coupling of a quantum emitter placed in near vicinity of the multilayer HMM slabs is investigated by introducing a mode-resolved LDOS calculation. The results show that HMM slabs with lower number of periods provide a higher LDOS and consequently a larger fluorescence transition rate enhancement factor. |
