Topological Optical Achirality

C. Wen, Z. Qi, J. Zhang +4

For arbitrary reciprocal single-mode structures, regardless of their geometric shapes or constituent materials, there must exist incident directions of plane waves for which they a…

Polarization-Independent Zero Directional Scattering Without Geometric Symmetries

Chunchao Wen, Zhichun Qi, Jianfa Zhang +3

As the characteristic feature of generalized Kerker effect in Mie theory, directional scattering elimination has been playing a pivotal role in nanophotonics and many other photoni…

Polarizations Underdescribe Vectorial Electromagnetic Waves

Chunchao Wen, Jianfa Zhang, Chaofan Zhang +3

Electromagnetic waves are described by not only polarization ellipses but also cyclically rotating vectors tracing out them. The corresponding fields are respectively directionless…

Intrinsic polarization conversion and avoided-mode crossing in X-cut lithium niobate microrings

Zelin Tan, Jianfa Zhang, Zhihong Zhu +4

Compared with well-developed free space polarization converters, polarization conversion between TE and TM modes in waveguide is generally considered to be caused by shape birefrin…

Magneto-chiral backscatterings by rotationally symmetric nonreciprocal structures

Chunchao Wen, Jianfa Zhang, Shiqiao Qin +2

It was proved that the joint operation of electromagnetic reciprocity and -fold () rotational symmetry would secure arbitrary polarization-independent backscattering eff…

Spatio-Temporal Nonlinear Theory in Birefringent Microrings

Zelin Tan, Xingqiao Chen, Ning Liu +5

Frequency-dependent nonlinear process in microresonators is widely acknowledged, but there is no theory available to calculate the conversion efficiency for each resonance of the r…
