Néel-type optical skyrmions inherited from evanescent electromagnetic fields with rotational symmetry
Bo Tian, Jingyao Jiang, Ningsheng Xu +7
Optical skyrmions, the optical analogue of topological configurations formed by three-dimensional vector fields covering the whole 4π solid angle but confined in a two-dimensional…
In-plane hyperbolic polariton tuners in terahertz and long-wave infrared regimes
Wuchao Huang, Thomas G. Folland, Fengsheng Sun +8
Development of terahertz (THz) and long-wave infrared (LWIR) technologies is mainly bottlenecked by the limited intrinsic response of traditional materials. Hyperbolic phonon polar…
Van der Waals phonon polariton microstructures for configurable infrared electromagnetic field localizations
Wuchao Huang, Fengsheng Sun, Zebo Zheng +7
Polar van der Waals (vdW) crystals that support phonon polaritons have recently attracted much attention because they can confine infrared and terahertz (THz) light to deeply subwa…
Controlling and focusing of in-plane hyperbolic phonon polaritons in α-MoO3 with plasmonic antenna
Zebo Zheng, Jingyao Jiang, Ningsheng Xu +5
Hyperbolic phonon polaritons (HPhPs) sustained in van der Waals (vdW) materials exhibit extraordinary capabilities of confining long-wave electromagnetic fields to the deep subwave…
Polariton Waveguide Modes in Two-Dimensional Van der Waals Crystals: An Analytical Model and Correlative Scanning Near-Field Optical Microscopy Studies
Fengsheng Sun, Wuchao Huang, Zebo Zheng +5
Two-dimensional van der Waals (vdW) crystals can sustain various types of polaritons with strong electromagnetic confinements, making them highly attractive for the nanoscale photo…
A mid-infrared biaxial hyperbolic van der Waals crystal
Zebo Zheng, Ningsheng Xu, Stefano Luigi Oscurato +10
Hyperbolic media have attracted much attention in the photonics community, thanks to their ability to confine light to arbitrarily small volumes and to their use for super-resoluti…
