Tomer's recent publication, Widely Tunable Infrared Antennas Using Free Carrier Refraction, was just published in Nano Letters. In this work we fabricate spherical Si and Ge nanoparticles and measure their associated infrared Mie resonances. We show that single nanoparticles can exhibit wavelength shifts arising from continuous doping-dependent tuning of the permittivity between dielectric (epsilon ~ 14) and metallic (epsilon ~ -20) regimes.

Nikita's paper, Hybrid Optical Antennas with Photonic Resistors, was just published in Optics Express. In this work, we simulate the infrared scattering properties of metal-semiconductor-metal split dipole antennas. We examine the change in scattering as the semicondcutor carrier concentration is varied between capacitive (low carrier density) and inductive/conductive (high carrier density) regimes. The most profound effects are seen at intermediate carrier densities where the semiconductor "load" acts as an efficient "photonic resistor", completely suppressing the scattering response.
