Cylindrical Vector Beam Multiplexing based on All‐Dielectric Fiber Meta‐Tips Enabling High‐Capacity Bidirectional Optical Communication

Laser &Photonics Reviews, EarlyView.
Cylindrical vector beam (CVB) multiplexing offers a viable solution to channel capacity, integration, and unidirectional transmission challenges in fiber‐rich sixth‐generation backbone networks. An all‐dielectric fiber meta‐tip‐enabled CVB multiplexing system is proposed and demonstrated, providing high‐capacity, bidirectional optical interconnects and

Nonlinear Distortion Equalization in Multi‐Span Optical Links Via a Feed‐Forward Photonic Neural Network

Laser &Photonics Reviews, EarlyView.
A feed‐forward photonic neural network equalizes linear and nonlinear impairments in multi‐span IMDD optical fiber transmission. The linear processing stage employs an 8‐tap optical Finite Impulse Response filter integrated on a silicon photonics platform, while the end‐of‐line photodetector represents the nonlinear stage.

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 ...
