Electric and magnetic excitation of coherent magnetic plasmon waves in a one-dimensional meta-chain.

Optics express

Zhu C, Liu H, Wang SM, Li T, Cao JX, Zheng YJ, Li L, Wang Y, Zhu SN, Zhang X.
PMID: 21164975
Opt Express. 2010 Dec 06;18(25):26268-73. doi: 10.1364/OE.18.026268.

A one-dimensional diatomic meta-chain with equal-size holes and different-length slits is designed. Broadband coherent magnetic plasmon waves (MPW) are formed in such a system, excited by both the electric resonance in the slits and the magnetic resonance in the...

Dressing plasmon resonance with particle-microcavity architecture for efficient nano-optical trapping and sensing.

Optics letters

PMID: 24562229
Opt Lett. 2014 Feb 15;39(4):873-6. doi: 10.1364/OL.39.000873.

We propose a particle-microcavity scheme for efficient optical trapping and sensing. When a resonant plasmonic nanoparticle (NP) is placed inside a microcavity with high Q-factor, sensitivity is enhanced in the far-field extinction while near-field around the NP is barely...

Opt Lett. 2011 Jan 15;36(2):247-9. doi: 10.1364/OL.36.000247.

A hybridization model for the localized surface plasmon resonance of a nanoshell is developed within the framework of long-wave approximation. Compared with the existing hybridization model derived from the hydrodynamic simulation of free electron gas, this approach is much...

Determination of the Excitation and Coupling Rates Between Light Emitters and Surface Plasmon Polaritons.

J Vis Exp. 2018 Jul 21;(137). doi: 10.3791/56735.

We have developed a unique method to measure the excitation and coupling rates between the light emitters and surface plasmon polaritons (SPPs) arising from metallic periodic arrays without involving time-resolved techniques. We have formulated the rates by quantities that...

Field-matter integral overlap to estimate the sensitivity of surface plasmon resonance biosensors.

Journal of the Optical Society of America. A, Optics, image science, and vision

J Opt Soc Am A Opt Image Sci Vis. 2012 Jul 01;29(7):1367-76. doi: 10.1364/JOSAA.29.001367.

We have analyzed the effectiveness of field-matter integral overlap between target index distribution and local near-fields to assess detection sensitivity of surface plasmon resonance (SPR) biosensors. The correlation of the overlap with sensitivity was clear. An overlap integral defined...

Optical Surface plasmon resonance (SPR) biosensors represent the most advanced and developed optical label-free biosensor technology. Optical SPR biosensors are a powerful detection and analysis tool that has vast applications in environmental protection, biotechnology, medical diagnostics, drug screening, food...

Surface plasmon resonance optical cavity enhanced refractive index sensing.

Giorgini A, Avino S, Malara P, Gagliardi G, Casalino M, Coppola G, Iodice M, Adam P, Chadt K, Homola J, De Natale P.
PMID: 23722800
Opt Lett. 2013 Jun 01;38(11):1951-3. doi: 10.1364/OL.38.001951.

We report on a method for surface plasmon resonance (SPR) refractive index sensing based on direct time-domain measurements. An optical resonator is built around an SPR sensor, and its photon lifetime is measured as a function of loss induced...

Probing complex reflection coefficients in one-dimensional surface plasmon polariton waveguides and cavities using STEM EELS.
