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…
Impact of Third Order Dispersion on Dissipative Soliton Resonance
Lujun Hong, Yazhou Wang, Abubakar Isa Adamu +5
Dissipative soliton resonance (DSR) is a promising way for high-energy pulse generation typically having a symmetrical square pulse profile. While this method is well known, the im…
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…
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…
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,…
Slow light,double directional rainbow trapping and releasing at terahertz frequencies
Jie Xu, Qian Shen, Kai Yuan +6
Slow light and rainbow trapping attract many attentions in last twenty years, and in most of the previous works, the researchers achieve the slow light and rainbow trapping with co…
Ultra-subwavelength focusing and giant magnetic-field enhancement in a low-loss one-way waveguide based on remanence
Jie Xu, Xiaohua Deng, Hang Zhang +4
The subwavelength focusing based on surface plasmon polaritons (SPP) has been widely explored in tapered metallic structures. However, the efficiency of energy localization is rela…
