Plasmons-the collective oscillations of valence electrons in conducting materials-possess a number of appealing properties for photonic technologies [1], the most salient of which are (1) their small spatial extension compared with the light wavelength, which has been exploited to achieve improved imaging resolution [2]; (2) their strong interaction with light, which is evidenced by a centenary tradition of generating colors through plasmon supporting metal nanoparticle suspensions [3]; and (3) the huge optical enhancements produced by this strong interaction, which upon external illumination result in near-field intensities > 105 times larger than the incident light intensity as inferred from 102Surface-enhanced Raman scattering (SERS) measurements [4]. Control over the spectral and spatial properties of these collective excitations has advanced at an impressive pace in recent years [5,6]. Equally impressive are their applications to ultrasensitive detection down to the single-molecule level [7], improved photovoltaics [8], nanoscale photometry [9], cancer therapy [10], and nonlinear optics [11], among other feats.
