Second harmonic generation in germanium quantum wells for nonlinear silicon photonics
Jacopo Frigerio, Chiara Ciano, Joel Kuttruff +12
Second-harmonic generation (SHG) is a direct measure of the strength of second-order nonlinear optical effects, which also include frequency mixing and parametric oscillations. Nat…
Ultrafast all-optical switching enabled by epsilon-near-zero modes in metal-insulator nanocavities
Joel Kuttruff, Denis Garoli, Jonas Allerbeck +5
Ultrafast control of light-matter interactions constitutes a crucial feature in view of new technological frontiers of information processing. However, conventional optical element…
Pump-probe Spectroscopy Study of Ultrafast Temperature Dynamics in Nanoporous Gold
Michele Ortolani, Andrea Mancini, Arne Budweg +3
We explore the influence of the nanoporous structure on the thermal relaxation of electrons and holes excited by ultrashort laser pulses ( fs) in thin gold films. Plasmon d…
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,…
