Tunable beam splitting via photorefractive nonlinearity and its applications in chiral waveguide induction and vortex generation
Hechong Chen, Zihan Liu, Shengdi Lian +6
We report experimental observation and theoretical explanation of novel propagation regimes for optical beams in an artificial nonlinear material with outstanding photorefractive p…
Anti-chiral edge states based on photonic Floquet lattices
Junying Wang, Xifeng Ji, Zhiwei Shi +5
Photonic Floquet lattices provide an excellent platform for manipulating different topologically protect-ed edge states. However, anti-chiral edge states have not been discussed mu…
Airy-soliton interactions in self-defocusing media with PT potentials
