Large spontaneous emission rate enhancement in grating coupled hyperbolic metamaterials
Hyperbolic metamaterial (HMM), a sub-wavelength periodic artificial structure with hyperbolic dispersion, can enhance the spontaneous emission of quantum emitters. Here, we demonstrate the large spontaneous emission rate enhancement of an organic dye placed in a grating coupled hyperbolic metamaterial (GCHMM). A two-dimensional (2D) silver diffraction grating coupled with an Ag/Al2O3 HMM shows ...
متن کاملthermal radiative properties of nanoscale semiconductors with incoherent formulation
rapid thermal processing (rtp) has become a key technology for semiconductor device manufacturing in a variety of applications, such as thermal oxidation, annealing, and thin-film growth. hence, understanding the radiative properties of silicon and other relevant materials is essential for the analysis of the thermal transport processes. we have analyzed and calculated the spectral, directional...
متن کاملTailoring Acoustic Metamaterials to Aeroacoustic Applications
The advent of metamaterials in acoustics is shaking-up the research community. The theoretical models and the realization technologies developed during the last decade have suddenly made possible applications that were barely conceivable before. Acoustic invisibility, perfect acoustic mirrors and lenses or ideal wave guides are now realizable with devices exploiting the potential of acoustic me...
متن کاملMicrolattice Metamaterials for Tailoring Ultrasonic Transmission with Elastoacoustic Hybridization
Materials with designed microscale architectures, like microlattices, can achieve extreme mechanical properties. Most studies of microlattices focus on their quasistatic response, but their structural dimensions naturally prime them for ultrasonic applications. Here we report that microlattices constitute a class of acoustic metamaterials that exploit elastoacoustic hybridization to tailor ultr...
متن کاملTailoring transparency of negative-index metamaterials with parametric amplification
The possibility of compensating losses in negative-index metatamterials doped by resonant four-level centers is shown based on quantum interference and extraordinary properties of parametric amplification of counterpropagating electromagnetic waves. ©2007 Optical Society of America OCIS codes: (1904410) Nonlinear optics, parametric processes, (270.1670) Coherent optical effects
