研究领域

Owing to the fundamental laws of diffraction, any dielectric system cannot focus light to a spot less than about half a wavelength of light (~λ/2). This diffraction limit imposes a lower limit of ~(/2)3 for the mode volume of a dielectric cavity, where is the wavelength of light inside the dielectric medium. Surface plasmons (SPs) can surpass [overcome，break]this diffraction limit by storing the electromagnetic energy partly in the kinetic energy of free electrons in conductors. This enables metallic nanostructures to concentrate light into deep-subwavelength volumes and to enhance the local density of states, which have propelled their use in a vast array of nanophotonics technologies and research endeavours[it has propelled use in a vast array of nanophotonics technologies and research endeavours because of the unprecedented abilities of nanometallic (that is, plasmonic) structures to concentrate light into deep-subwavelength volumes and to largely enhance the local density of states.]. After a rapid development in the past decades, plasmonics is now covering a broad range of branches, including information technology, biological/chemical sensing, medical therapy, renewable energy, and super-resolution imaging, etc.
