Spectroscopic and Interferometric Sum-Frequency Imaging of Strongly Coupled Phonon Polaritons in SiC Metasurfaces
Richarda Niemann, Niclas S. Mueller, Sören Wasserroth +4
Phonon polaritons enable waveguiding and localization of infrared light with extreme confinement and low losses. The spatial propagation and spectral resonances of such polaritons…
Elucidating the Mechanism of Large Phosphate Molecule Intercalation Through Graphene Heterointerfaces
Jiayun Liang, Ke Ma, Xiao Zhao +19
Intercalation is a process of inserting chemical species into the heterointerfaces of two-dimensional (2D) layered materials. While much research has focused on intercalating metal…
Infrared super-resolution wide-field microscopy using sum-frequency generation
Richarda Niemann, Sören Wasserroth, Guanyu Lu +6
Super-resolution microscopy in the visible is an established powerful tool in several disciplines. In the infrared (IR) spectral range, however, no comparable schemes have been dem…
Multi-frequency coherent emission from superstructure thermal emitters
Guanyu Lu, Marko Tadjer, Joshua D. Caldwell +1
Long-range spatial coherence can be induced in thermal emitters by embedding a periodic grating into a material supporting propagating polaritons or dielectric modes. However, the…
Vibrational Coupling to Epsilon-Near-Zero Waveguide Modes
Thomas G. Folland, Guanyu Lu, A. Bruncz +3
Epsilon near zero modes offer extreme field enhancement that can be utilized for developing enhanced sensing schemes. However, demonstrations of enhanced spectroscopies have largel…
