Direct measurement of broken time-reversal symmetry in centrosymmetric and non-centrosymmetric atomically thin crystals with nonlinear Kerr rotation
Florentine Friedrich, Paul Herrmann, Shridhar Sanjay Shanbhag +3
Time-reversal symmetry, together with space-inversion symmetry, is one of the defining properties of crystals, underlying phenomena such as magnetism, topology and non-trivial spin…
Ultrafast Coherent Bandgap Modulation Probed by Parametric Nonlinear Optics
Sebastian Klimmer, Thomas Lettau, Laura Valencia Molina +5
Light-matter interactions in crystals are powerful tools that seamlessly allow both functionalities of sizeable bandgap modulation and non-invasive spectroscopy. While we often ass…
Ultrafast all-optical second harmonic wavefront shaping
A. Sinelnik, S. H. Lam, F. Coviello +6
Optical communication can be revolutionized by encoding data into the orbital angular momentum of light beams. However, state-of-the-art approaches for dynamic control of complex o…
Valley Polarization-Electric Dipole Interference and Nonlinear Chiral Selection Rules in Monolayer WSe
Paul Herrmann, Sebastian Klimmer, Till Weickhardt +6
In monolayer transition metal dichalcogenides time-reversal symmetry, combined with space-inversion symmetry, defines the spin-valley degree of freedom. As such, engineering and co…
All-optical polarization and amplitude modulation of second-harmonic generation in atomically thin semiconductors
Sebastian Klimmer, Omid Ghaebi, Ziyang Gan +4
Second-harmonic generation is of paramount importance in several fields of science and technology, including frequency conversion, self-referencing of frequency combs, nonlinear sp…
