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…
Unraveling Ultrafast Photoionization in Hexagonal Boron Nitride
Lianjie Xue, Song Liu, Yang Hang +17
The non-linear response of dielectrics to intense, ultrashort electric fields has been a sustained topic of interest for decades with one of its most important applications being f…
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…
Guided Mid-IR and Near-IR Light within a Hybrid Hyperbolic-Material/Silicon Waveguide Heterostructure
Mingze He, Sami I. Halimi, Thomas G. Folland +6
Silicon waveguides have enabled large-scale manipulation and processing of near-infrared optical signals on chip. Yet, expanding the bandwidth of guided waves to other frequencies…
Lithography-free IR polarization converters via orthogonal in-plane phonons in a-MoO3 flakes
Sina Abedini Dereshgi, Thomas G. Folland, Akshay A. Murthy +5
Exploiting polaritons in natural vdW materials has been successful in achieving extreme light confinement and low-loss optical devices and enabling simplified device integration. R…
Ultrastrong plasmon-phonon coupling via epsilon-near-zero nanocavities
Daehan Yoo, Fernando de León-Pérez, In-Ho Lee +6
Vibrational ultrastrong coupling (USC), where the light-matter coupling strength is comparable to the vibrational frequency of molecules, presents new opportunities to probe the in…
