Tunable all-optical logic gates based on nonreciprocal topologically protected edge modes
Jie Xu, Panpan He, Delong Feng +4
All-optical logic gates have been studied intensively for their potential to enable broadband, low-loss, and high-speed communication. However, poor tunability has remained a key c…
Realization of broadband index-near-zero modes in nonreciprocal magneto-optical heterostructures
Yun Zhou, Panpan He, Sanshui Xiao +5
Epsilon-near-zero (ENZ) metamaterial with the relative permittivity approaching zero has been a hot research subject in the past decades. The wave in the ENZ region has infinite ph…
Realization of broadband truly rainbow trapping in gradient-index heterostructures
Jie Xu, Sanshui Xiao, Panpan He +5
Unidirectionally propagating waves (UPW) such as topologically protected edge modes and surface magnetoplasmons (SMPs) has been a research hotspot in the last decades. In the study…
Slow wave and truly rainbow trapping in one-way terahertz waveguide
Jie Xu, Panpan He, Delong Feng +4
Slow or even stop electromagnetic (EM) waves attract researchers' attentions for its potential applications in energy storage, optical buffer and nonlinearity enhancement. However,…
