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…
Controlled Polar Asymmetry of Few-Cycle and Intense Mid-Infrared Pulses
Christian Schmidt, Johannes Bühler, Bernhard Mayer +3
We demonstrate synthesis of super-octave-spanning and phase-locked transients in the multi-terahertz frequency range with amplitudes exceeding 13 MV/cm. Sub-cycle polar asymmetry o…
Tunneling Breakdown of a Strongly Correlated Insulating State in VO Induced by Intense Multi-Terahertz Excitation
B. Mayer, C. Schmidt, A. Grupp +8
We directly trace the near- and mid-infrared transmission change of a VO thin film during an ultrafast insulator-to-metal transition triggered by high-field multi-terahertz tra…
Non-perturbative Interband Response of InSb Driven Off-resonantly by Few-cycle Electromagnetic Transients
F. Junginger, B. Mayer, C. Schmidt +5
Intense multi-THz pulses are used to study the coherent nonlinear response of bulk InSb by means of field-resolved four-wave mixing spectroscopy. At amplitudes above 5 MV/cm the si…
