Three-dimensional random dielectric colloid metamaterial with giant isotropic optical activity

Viktar Asadchy, Cheng Guo, Ihar Faniayeu +1

Motivated by the theoretical observation that isotropic chirality can exist even in completely random systems, we design a dielectric metamaterial consisting of a random colloid of…

Sub-Wavelength Passive Optical Isolators Using Photonic Structures Based on Weyl Semimetals

Viktar Asadchy, Cheng Guo, Bo Zhao +1

We design sub-wavelength high-performing non-reciprocal optical devices using recently discovered magnetic Weyl semimetals. These passive bulk topological materials exhibit anomalo…
