Enhancement of surface plasmons in an Ag aggregate by optical gain in a dielectric medium.
نویسندگان
چکیده
We have observed the compensation of loss in a metal by a gain in a dielectric medium in the mixture of an Ag aggregate and a Rhodamine 6G dye. The demonstrated sixfold enhancement of the Rayleigh scattering is the evidence of the enhancement of the surface-plasmon resonance. The reported experimental observation facilitates many applications of nanoplasmonics.

Surface plasmons at nanoscale relief gratings between a metal and a dielectric medium with optical gain
Surface plasmons at the interface between metal and a dielectric with strong optical amplification are analyzed theoretically. It is shown that proper choice of optical indices of the dielectric medium results in an infinitely large effective refractive index of surface waves. Such resonant plasmons have extremely low group velocity and are localized within a vanishingly small distance near the...
متن کاملTunable Dipole Surface Plasmon Resonances of Silver Nanoparticles by Cladding Dielectric Layers
The tunability of surface plasmon resonance can enable the highest degree of localised surface plasmon enhancement to be achieved, based on the emitting or absorbing wavelength. In this article, tunable dipole surface plasmon resonances of Ag nanoparticles (NPs) are realized by modification of the SiO2 dielectric layer thicknesses. SiO2 layers both beneath and over the Ag NPs affected the reson...

Periodic dielectric structures are typically integrated with a planar waveguide to create photonic band-edge modes for feedback in one-dimensional distributed feedback lasers and two-dimensional photonic-crystal lasers. Although photonic band-edge lasers are widely used in optics and biological applications, drawbacks include low modulation speeds and diffraction-limited mode confinement. In co...

متن کاملCoupling discrete metal nanoparticles to photonic crystal surface resonant modes and application to Raman spectroscopy.
Coupling a tightly packed layer of discrete metal nanoparticles to the resonant mode of a photonic crystal surface has been demonstrated as a means for obtaining additional electromagnetic gain for surface-enhanced Raman spectroscopy (SERS), in which electric fields of the photonic crystal can couple to plasmon resonances of the metal nanoparticles. Because metal nanoparticles introduce absorpt...
