“…In this work, our aim is to directly observe the electromagnetic field distribution using a scanning near-field optical microscope (SNOM). Recently, many SNOM experiments have been performed on isolated or coupled nanostructures, [17][18][19][20] but only very few studies have been achieved on arrays. Salerno et al 21 and Salomon et al 22 observed the localization of light on an array of gold nanoparticles with a SNOM, but the structures were separated from each other by one micrometer, which makes them almost isolated from each other.…”

By scanning near-field optical microscopy, we measured the localization of the electromagnetic field on an array of gold nanodisks illuminated in a transmission mode. We experimentally observed that the field is localized between the disks, with a pattern oriented along the incident polarization direction. We also observed that the electromagnetic field rapidly decays above the nanodisks, showing a strong vertical localization. The experimental results are in good agreement with numerical simulations performed by a finite difference time domain method. This study provides quantitative information about the local optical properties of closely-packed nanodisks that can be used for applications in biochemical sensors and nanolithography.

“…Typically, only resonant field modes extend far and strongly enough into space to allow sufficient probe-sample separation. [26][27][28][29] On the plus side, SNOM readily offers spectroscopic capabilities, 30-34 the discrimination of two orthogonal polarization states [35][36][37] and time-resolved measurements. 38 With a careful preparation and independent characterization of the detecting probe it might become feasible to study unknown samples.…”

Resonant nanoplasmonic structures have long been recognized for their unique applications in subwavelength control of light for enhanced transmission, focussing, field confinement, decay rate management, etc. Increasingly, they are also integrated in electro-optical analytical sensors, shrinking the active volume while at the same time improving sensitivity and specificity. The microscopic imaging of resonances in such structures and also their dynamic variations has seen dramatic advances in recent years. In this Minireview we outline the current status of this rapidly evolving field, discussing both optical and electron microscopy approaches, the limiting issues in spatial resolution and data interpretation, the quantities that can be recorded, as well as the growing importance of time-resolving methods.

“…(2) Means of writing the input and reading the output in the nanoscale are experimentally established. 23,31,32 (3) The entirely classical operation implies that creation and maintenance of entanglement are not necessary. (4) Metal nanoparticle can be prepared in large arrays in a controllable fashion.…”

We propose and illustrate numerically a class of nanoscale, ultrafast logic gates with the further advantage of reconfigurability. Underlying the operation of the gates and their versatility is the concept of polarization control of the electromagnetic energy propagating via metal nanoparticle arrays. Specifically, a set of different logic gates is shown to obtain from a single metal nanoparticle junction by modification of the polarization properties of the input light sources. Implications and extensions of the gates are discussed.
