Strong optical nonreciprocity in a photonic crystal composed of spinning cylinders
Hengzhi Li, Wanyue Xiao, Junho Jung +2
Moving media break time-reversal symmetry and exhibit intriguing optical nonreciprocity. This nonreciprocity is usually weak due to the much lower moving speed of media relative to…

Directional sources realised by toroidal dipoles
Junho Jung, Yuqiong Cheng, Wanyue Xiao +1
Directional optical sources can give rise to the directional excitation and propagation of light. The directionality of the conventional directional dipole (CDD) sources are attrib…
