Flexible Silicon Dimer Nanocavity with Electric and Magnetic Enhancement

High-index dielectrics have recently been regarded as promising building blocks in nanophotonics owing to optical electric and magnetic Mie resonances. In particular, silicon is gaining great interest the backbone of modern technology. Here, dimer nanocavities with different sizes nanospheres were constructed using a probe nanomanipulation method interacted few-layered R6G membrane investigate enhancement mode coupling. The evidence fluorescence slightly prolonged lifetime indicated existence nanocavities. addition, simulated field distributions decomposed nanocavity used analyze contribution modes enhanced fluorescence. Such flexible has applications sensing all-dielectric metamaterials or nanophotonic devices.
