Squeeze free space with nonlocal flat optics
Cheng Guo, Haiwen Wang, Shanhui Fan
There has been substantial interest in miniaturizing optical systems by flat optics. However, one essential optical component, free space, fundamentally cannot be substituted with…

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…
