Beam Routing through Excitons in Transition Metal Dichalcogenide Monolayers
Yonas Lebsir, Jacob Terndrup Heiden, Jorge Barcia Rodríguez +6
Routing light at the nanoscale typically relies on nanostructured surfaces to imprint directionality on the emission. Using low-temperature, angle-resolved cathodoluminescence spec…
Local control and lateral nanofocusing of hyperbolic phonon polaritons
Jacob T. Heiden, Haozhe Tong, Yongjun Lim +6
Phonon polaritons in van der Waals crystals enable exceptional light confinement and control over low-loss nanolight propagation. The polariton wavelength can be controlled by the…
Bloch phonon-polaritons with anomalous dispersion in polaritonic Fourier crystals
Sergey G. Menabde, Yongjun Lim, Alexey Y. Nikitin +5
The recently suggested concept of a polaritonic Fourier crystal (PFC) is based on a harmonically-corrugated mirror substrate for a thin pristine polaritonic crystal layer. The prop…
Prospects to bypass nonlocal phenomena in metals using phonon-polaritons
Jacob T. Heiden, Eduardo J. C. Dias, Minhyuk Kim +6
Electromagnetic design relies on an accurate understanding of light-matter interactions, yet often overlooks electronic length scales. Under extreme confinement, this omission can…
Polaritonic Fourier crystal
Sergey G. Menabde, Yongjun Lim, Kirill Voronin +4
Polaritonic crystals - periodic structures where the hybrid light-matter waves called polaritons can form Bloch states - promise a deeply subdiffractional nanolight manipulation an…
Fourier analysis of near-field patterns generated by propagating polaritons
Minsoo Jang, Sergey G. Menabde, Fatemeh Kiani +5
Scattering-type scanning near-field optical microscope (s-SNOM) has become an essential tool to study polaritons - quasiparticles of light coupled to collective charge oscillations…
High-index and low-loss topological insulators for mid-infrared nanophotonics
Sergey G. Menabde, Jacob T. Heiden, Vladimir A. Zenin +2
Topological insulators generally have dielectric bulk and conductive surface states. Consequently, some of these materials have been shown to support polaritonic modes at visible a…
Image polaritons in van der Waals crystals
Sergey G. Menabde, Jacob T. Heiden, Joel Cox +2
Polaritonic modes in low-dimensional materials enable strong light-matter interactions and provide a platform for light manipulation at nanoscale. Very recently, a new class of pol…
Near-field probing of image phonon-polaritons in hexagonal boron nitride on gold crystals
Sergey G. Menabde, Sergejs Boroviks, Jongtae Ahn +7
Near-field mapping has been widely used to study hyperbolic phonon-polaritons in van der Waals crystals. However, an accurate measurement of the polaritonic loss remains challengin…
Real-space imaging of acoustic plasmons in large-area CVD graphene
Sergey G. Menabde, In-Ho Lee, Sanghyub Lee +8
An acoustic plasmonic mode in a graphene-dielectric-metal heterostructure has recently been spotlighted as a superior platform for strong light-matter interaction. It originates fr…
