Valley-dependent wavepacket self-rotation and Zitterbewegung in symmetry-broken honeycomb lattices
Xiuying Liu, Frane Lunić, Daohong Song +6
The toolbox quantities used for manipulating the flow of light include typically amplitude, phase, and polarization. Pseudospins, such as those arising from valley degrees of freed…
Nonlinear control of PT-symmetry and non-Hermitian topological states
Shiqi Xia, Dimitrios Kaltsas, Daohong Song +6
Advances in topological photonics and non-Hermitian optics have drastically changed our perception on how interdisciplinary concepts may empower unprecedented applications. Bridgin…
Nontrivial coupling of light into a defect: the interplay of nonlinearity and topology
Shiqi Xia, Dario Jukić, Nan Wang +9
The flourishing of topological photonics in the last decade was achieved mainly due to developments in linear topological photonic structures. However, when nonlinearity is introdu…
Optically Addressed Spatial Light Modulator based on Nonlinear Metasurface
Shengchao Gong, Mengxin Ren, Wei Wu +2
Spatial light modulators (SLMs) are devices for modulating amplitude, phase or polarization of a light beam on demand. Such devices have been playing an indispensable inuence in ma…
Resonantly tunable second harmonic generation from lithium niobate metasurfaces
Junjun Ma, Fei Xie, Weijin Chen +7
Second harmonic generation (SHG) is a coherent nonlinear phenomenon that plays an important role in laser color conversion. Lithium niobate (LN), which features both a large band g…
