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…
Defect-induced nonlinearity in 2D nanoparticles
Jie Xu, Eric Plum
Optical nonlinearity depends on symmetry and symmetries vanish in the presence of defects. Vaccancy defects in centrosymmetric crystals and thin films are a well-known source of ev…
Toy model of harmonic and sum frequency generation in 2D nanostructures
Jie Xu, Vassili Savinov, Eric Plum
Optical nonlinearities of matter are often associated with the response of individual atoms. Here, using a toy oscillator model, we show that in the confined geometry of a two-dime…
Broadband energy squeezing and tunneling based on unidirectional modes
Lujun Hong, Yazhou Wang, Yun Shen +4
Energy squeezing attracts many attentions for its potential applications in electromagnetic (EM) energy harvesting and optical communication. However, due to the Fabry-Perot resona…
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,…
