Difficulties of the traditional PhC-based superprisms
Wei Li, Xiaogang Zhang, Xulin Lin +1
This paper is to discuss the difficulties of the traditional photonic crystals (PhC) -based superprisms.
Switchable Hyperbolic Metamaterials With Magnetic Control
Wei Li, Zheng Liu, Xiaogang Zhang +1
A switchable hyperbolic material (SHM) is investigated, with which one can turn on or off the hyperbolic dispersion of the material via magnetic control. The SHM has simple structu…
Confined one-way mode at magnetic domain wall for broadband high-efficiency one-way waveguide, splitter and bender
Xiaogang Zhang, Wei Li, Xunya Jiang
We find the one-way mode can be well-confined at the magnetic domain wall by the photonic bandgap of gyromagnetic bulk material. Utilizing the well-confined one-way mode at the dom…
Evolutions of helical edge states in disordered HgTe/CdTe quantum wells
Liang Chen, Qin Liu, Xulin Lin +2
We study the evolutions of the nonmagnetic disorder-induced edge states with the disorder strength in the HgTe/CdTe quantum wells. From the supercell band structures and wave-funct…
