متن کاملRadiative Enhancement of Plasmonic Nanopatch Antennas
Efficient light manipulation at subwavelength scale is of great interest for solar energy conversion, optical sensing, and nanophotonic devices. Recently, plasmonic nanopatch antennas (PNAs), which consist of plasmonic nanoparticles and metal films with thin layers of dielectric spacers sandwiched between them, have shown promise for directing and enhancing radiation from the dipole emitters at...

Utilizing boundary integral method (BIM), we investigate molecularspontaneous emission rate enhancement in the vicinity of plasmonic nanoparticles ofelliptical cross section. These types of nanoparticles can considerably enhance themolecule decay rate. The spontaneous emission rate can be modified by altering theaspect ratio of the elliptical nanoparticle, the background refractive index andnan...
متن کاملOptical antenna enhanced spontaneous emission.
Atoms and molecules are too small to act as efficient antennas for their own emission wavelengths. By providing an external optical antenna, the balance can be shifted; spontaneous emission could become faster than stimulated emission, which is handicapped by practically achievable pump intensities. In our experiments, InGaAsP nanorods emitting at ∼ 200 THz optical frequency show a spontaneous ...
متن کاملUltrafast spontaneous emission source using plasmonic nanoantennas
Typical emitters such as molecules, quantum dots and semiconductor quantum wells have slow spontaneous emission with lifetimes of 1-10 ns, creating a mismatch with high-speed nanoscale optoelectronic devices such as light-emitting diodes, single-photon sources and lasers. Here we experimentally demonstrate an ultrafast (<11 ps) yet efficient source of spontaneous emission, corresponding to an e...
