Enhanced spontaneous emission inside hyperbolic metamaterials.
TLDR
To extract the plasmonic modes of the structure into the far field, two types of 1D grating with triangular and rectangular profile are implemented, obtaining a 10-fold radiative enhancement at visible frequencies.Abstract:
Hyperbolic metamaterials can enhance spontaneous emission, but the radiation-matter coupling is not optimized if the light source is placed outside such media. We demonstrate a 3-fold improvement of the Purcell factor over its outer value and a significant enlargement in bandwidth by including the emitter within a Si/Ag periodic multilayer metamaterial. To extract the plasmonic modes of the structure into the far field we implement two types of 1D grating with triangular and rectangular profile, obtaining a 10-fold radiative enhancement at visible frequencies.read more

TL;DR: The large spontaneous emission rate enhancement of an organic dye placed in a grating coupled hyperbolic metamaterial (GCHMM) is demonstrated and it is confirmed that the observed enhancement of GCHMM is due to the outcoupling of non-radiative plasmonic modes as well as strong plAsmon-exciton coupling in HMM via diffracting grating.
