1Nanoscale all-optical devices based on surface plasmon polaritons显示文摘Surface plasmon polariton,a kind of surface electromagnetic wave propagating along the interface between metals and dielectrics,provides an excellent platform for the realization of integrated photonic devices due to its unique properties of confining light into subwavelength scales.Our recent research progresses of nanoscale integrated photonic devices based on surface plasmon polaritons,including all-optical switches,all-optical logic discriminator,and all-optical routers,are introduced in detail.Jianjun Chen Chengwei Sun Xiaoyong Hu 2014Chinese Science Bulletin2014,59,22:4
2Frontiers of plasmonics显示文摘Surface plasmons are quanta of collective oscillations of free electrons at metal-insulator interface, usually excited by pho-tons. Since it was first proposed in 1950s by Ritchie, new interests have been aroused due to recent advances in synthe-sis and fabrication of various nanostructures.XU HongXing 2010Chinese Science Bulletin2010,55,24:1
3Conic hyperspectral dispersion mapping applied to semiconductor plasmonics显示文摘The surface plasmon resonance tracking over metal surfaces is a well-established,commercially available,biochemical quantification tool primarily applied in research.The utilization of such a tool is,however,constrained to highly specialized industries,capable of justifying the human and instrumental resource investments required by the characterization method.We have proposed to expand the field of application of this biosensing approach by redesigning this method through the integration and miniaturization within a semiconductor platform.Uncollimated and broadband emission from a light-emitting semiconductor is employed to couple a continuum of surface plasmon modes over a metal–dielectric architecture interfaced with a GaAs–AlGaAs substrate.A tensor version of rigorous coupled wave theory is employed to optimize the various fabrication specifications and to predict the light scatterings over a wide range of variables.We then present a hyperspectral characterization microscope capable of directly mapping the dispersion relation of scattered light,including diffracted surface plasmons,as an intensity distribution versus photon energy and surface wavevectors.Measurements carried out in a buffered solution demonstrate the accurate description of the uncollimated and broadband surface plasmon states.Finally,we introduce a simplified method of dispersion mapping,in which quasi-conic cross-sections of the light’s scattering can be acquired directly,thus monitoring surficial responses in as fast as 1.2 s.This is over 300 times faster than required by implementing full dispersion mapping.While compromising on the volume of collected information,this method,combined with the solid-state integration of the platform,shows great promise for the fast detection of biochemical agents.Dominic Lepage Alvaro Jimenez Jacques Beauvais Jan J Dubowski 2012Light(Science & Applications)2012,1,1:0
