Asymmetric optical transmission is fundamental and highly desirable in information
processing and full manipulation of lightwave. We here propose an asymmetric optical …

Photonic skyrmions characterized by topological nontrivial electromagnetic textures have
triggered enormous interest, exhibiting promising applications in optical information storage …

We have studied the dependence of the rotation angle and ellipticity on the sample
orientation and incident polarization from metallic nanohole arrays. The arrays have fourfold …

Fullerene-based micro/nano-architectures (FMNAs) with remarkable photoluminescence
(PL) emissions have attracted considerable interest as potential building blocks for optical …

The broken mirror symmetry in subwavelength photonic systems has manifested many
interesting chiroptical effects, such as optical rotation and circular dichroism. When such …

The physical origins of chiroptical responses from artificial optically active media are
significant for developing high-performance circular dichroism (CD) spectroscopic …

When two degenerate surface plasmon polariton (SPP) modes couple, in addition to the
creation of plasmonic band gap, their respective decay rates are modified as well, resulting …

Metallic grating structures have been shown to provide an effective platform for generating
hot electrons and driving electrochemical reactions. Here, we present a systematic …

In analogy to the Su-Schrieffer-Heeger (SSH) model, one-dimensional (1D) electromagnetic
(EM) crystals can exhibit nontrivial topological properties. When a nontrivial EM crystal is in …

A frequency-region selective light absorber is theoretically investigated by an electro-optical
waveguide cavity coupled plasmonic micro-structure. A spectrally separated broadband …
