Nanostructuring is a key element for the development of optics, optoelectronics, and photonics capable of operating on subwavelength scales. However, the realization of highly integrated optical devices and sensors with nanolocal electromagnetic field control requires structural elements comparable to and smaller than a wavelength of light. One widely investigated approach is to use appropriately designed metallic and metallodielectric nanostructures to manipulate light in the form of various surface plasmon excitations, such as surface plasmon polaritons and localized surface plasmons.1 These electromagnetic surface modes are associated with the coherent excitation of the free-electron density charge waves at the interface of a metal and a dielectric material. Various plasmonic circuit elements based on nanostructured metal films, such as waveguides, mirrors, lenses, resonators, and plasmonic crystals, have been designed and tested. Plasmonic nanostructures can provide both passive and active all-optical elements, the latter capable of operating at low-control light intensities due to the electromagnetic field enhancement resulting from plasmonic excitations.2 Alternative plasmonics can be developed based on discrete sets of interacting metallic particles. We have recently developed an approach to inexpensively fabricate large arrays (1cm2 with up to 1 billion nanorods) of aligned nanoscale metallic rods attached to a substrate.3 Typically, the nanorods have a diameter of some 20nm with length controllable between 50 and 450nm. These are required to tailor the linear and nonlinear behavior of plasmonic excitations. However, to develop their functionalities and integrate them in complex plasmonic circuits for sensing and telecommunication applications, the nanorod assemblies must be configured in various shapes. An attractive solution is to use femtosecond laser-based direct writing technology to restructure free-standing nanorods and Figure 1.
