Mid Infrared Nonlinear Plasmonics using Germanium Nanoantennas on Silicon Substrates
Marco P. Fischer, Aaron Riede, Kevin Gallacher +8
We demonstrate third harmonic generation in plasmonic antennas made of highly doped germanium and designed to be resonant in the mid infrared. Owing to the near-field enhancement,…
Optical Activation of Germanium Plasmonic Antennas in the Mid Infrared
Marco P. Fischer, Christian Schmidt, Emilie Sakat +9
Impulsive interband excitation with femtosecond near-infrared pulses establishes a plasma response in intrinsic germanium structures fabricated on a silicon substrate. This direct…
Tunability and Losses of Mid-infrared Plasmonics in Heavily Doped Germanium Thin Films
Jacopo Frigerio, Andrea Ballabio, Giovanni Isella +16
Heavily-doped semiconductor films are very promising for application in mid-infrared plasmonic devices because the real part of their dielectric function is negative and broadly tu…
