Terahertz Twistoptics -- engineering canalized phonon polaritons
Maximilian Obst, Tobias Nörenberg, Gonzalo Álvarez-Pérez +11
The terahertz (THz) frequency range is key to study collective excitations in many crystals and organic molecules. However, due to the large wavelength of THz radiation, the local…
Modeling nonlinear optical interactions of focused beams in bulk crystals and thin films: A phenomenological approach
Kai J. Spychala, Zeeshan H. Amber, Lukas M. Eng +1
Coherent nonlinear optical micro-spectroscopy is a frequently used tool in modern material science, as it is sensitive to many different local observables, which comprise, among ot…
Germanium monosulfide as a natural platform for highly anisotropic THz polaritons
Tobias Nörenberg, Gonzalo Álvarez-Pérez, Maximilian Obst +8
Terahertz (THz) electromagnetic radiation is key to optically access collective excitations such as magnons (spins), plasmons (electrons), or phonons (atomic vibrations), thus brid…
Quantifying the Coherent Interaction Length of Second-Harmonic Microscopy in Lithium Niobate Confined Nanostructures
Zeeshan Hussain Amber, Benjamin Kirbus, Lukas M. Eng +1
Thin-film lithium niobate (TFLN) in the form of x- or z-cut lithium-niobate-on-insulator (LNOI) has recently popped up as a very promising and novel platform for developing integra…
Near-field examination of perovskite-based superlenses and superlens-enhanced probe-object coupling
Susanne C. Kehr, Yongmin M. Liu, L. W. Martin +11
A planar slab of negative index material works as a superlens with sub-diffraction-limited imaging resolution, since propagating waves are focused and, moreover, evanescent waves a…
