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…
