Spectral narrowing of a phonon resonance in time-domain sum-frequency spectroscopy
Riko Kiessling, Martin Wolf, Alexander Paarmann
Sum-frequency generation (SFG) spectroscopy provides a versatile method for the investigation of non-centrosymmetric media and interfaces. Here, using tunable picosecond infrared (…
Layer-Resolved Resonance Intensity of Evanescent Polariton Modes in Anisotropic Multilayers
Nikolai Christian Passler, Giulia Carini, Dmitry N. Chigrin +1
Phonon polariton modes in layered anisotropic heterostructures are a key building block for modern nanophotonic technologies. The light-matter interaction for evanescent excitation…
Second Harmonic Generation from Grating-Coupled Hybrid Plasmon-Phonon Polaritons
Marcel Kohlmann, Christian Denker, Nikolai C. Passler +4
Polaritons can provide strong optical field enhancement allowing to boost light-matter interaction. Here, we experimentally observe enhancement of mid-infrared second-harmonic gene…
