Kurzfassung englisch:
Nanoslits are an effective way to couple free-space light into a plasmonic system, by launching surface plasmon polaritons (SPP) [1]. Light-SPP coupling strongly depends on polarization, nanoslit width, and laser wavelength and has been studied for systems with fixed geometries. Here, we present a plasmonic nanoslit that is integral part of a nanoelectromechanial system, creating a anoplasmomechanical system, which allows us to dynamically control the nanoslit
(Fig. 1a). Our initial results were obtained with two gold-covered nanomechanical silicon nitride (SiN) strings featuring a nanoslit in the center. The nanoslit was fabricated by focused ion beam milling, which guarantees a high parallelism (Fig. 1b). When passing an oscillating current through one of the strings, we can drive this string at resonance with the created Lorentz force with amplitudes that are large enough to completely close the gap.
