Abstract
Plasmonics provides an elegant way to effectively couple optical radiation to single sub-wavelength quantum systems [1]. In particular, the mid-infrared vibrational fingerprint region is of particular interest for sensing large molecules of biological relevance. In this context, we introduce germanium as a novel material for active mid-IR plasmonics. Semiconductors offer the possibility to tune the plasma frequency by selection of the doping level. Moreover, the same effect can be achieved by ultrafast near-IR excitation of electron-hole pairs in intrinsic Ge [2]. This approach gives us full optical control over the plasmonic resonance in nanoantennas.
