Customizing 3D Polarization Structures at Second Harmonic Frequency
Laser &Photonics Reviews, EarlyView.The nonlinear optical metasurfaces that can generate second harmonic waves (SHWs) and manipulate 3D polarization structures are designed and fabricated. Based on the concept of nonlinear geometric phase, the desired phase distributions of the SHWs are encoded onto the metasurfaces by using gold C3 meta‐atoms.

Tunable Topological Directional Supercoupler and Applications in THz On‐Chip Communication
Laser &Photonics Reviews, EarlyView.A topological directional supercoupler is demonstrated, enabling dual‐channel 50 Gbps on‐chip terahertz communication with phototunable power splitting ratios. The achieved sub‐wavelength scale coupling area, sharp waveguide bends, and momentum‐conserved coupling process allow for ultra‐compact and efficient terahertz topological photonic integrated ...

Vortex Beam Lasing from III‐V Nanowires Epitaxially Grown on Silicon‐on‐Insulator
Laser &Photonics Reviews, EarlyView.An epitaxially grown InGaAs nanowire photonic crystal laser on silicon‐on‐insulator is demonstrated to emit vortex beams carrying orbital angular momentum. Deforming the honeycomb lattice causes the band inversion effect and creates symmetry‐protected bound states in the continuum, enabling single‐mode lasing with a topological charge of −2 ...
