Manipulation and steering of hyperbolic surface polaritons in hexagonal boron nitride
S. Dai, M. Tymchenko, Y. Yang +8
Hexagonal boron nitride (hBN) is a natural hyperbolic material that supports both volume-confined hyperbolic polaritons (HPs) and sidewall-confined hyperbolic surface polaritons (H…
Ultra-low-loss Polaritons in Isotopically Pure Materials: A New Approach
Alexander J. Giles, Siyuan Dai, Igor Vurgaftman +12
Conventional optical components are limited to size-scales much larger than the wavelength of light, as changes in the amplitude, phase and polarization of the electromagnetic fiel…
Relative efficiency of polariton emission in two-dimensional materials
Siyuan Dai, Qiong Ma, Yafang Yang +15
We investigated emission and propagation of polaritons in a two dimensional van der Waals material hexagonal boron nitride (hBN). Our specific emphasis in this work is on hyperboli…
Mechanical detection and imaging of hyperbolic phonon polaritons in hexagonal Boron Nitride
Antonio Ambrosio, Luis A. Jauregui, Siyan Dai +7
Mid-infrared nano-imaging and spectroscopy of two-dimensional (2D) materials have been limited so far to scattering-type Scanning Near-field Optical Microscopy (s-NSOM) experiments…
Faraday rotation due to surface states in the topological insulator (BiSb)Te
Yinming Shao, Kirk W. Post, Jhih-Sheng Wu +9
Using magneto-infrared spectroscopy, we have explored the charge dynamics of (Bi,Sb)Te thin films on InP substrates. From the magneto-transmission data we extracted three d…
