Laser &Photonics Reviews, EarlyView.When a uniform field interacts with a complex medium, it becomes scattered into a nonuniform distribution. A mode‐integration metamaterial employs its intrinsic controlled disorder to coherently reorganize and integrate the scattered field components into a tailored modal output, establishing a new paradigm for programmable modal coupling and versatile

Terahertz All‐Dielectric Maxwell Fisheye Lens Waveguide Crossings via Transformation Optics
Laser &Photonics Reviews, EarlyView.All‐silicon terahertz waveguide crossings based on Maxwell fisheye lenses are reshaped using transformation optics to interface with planar waveguides while reducing mode mismatch. Realized via subwavelength perforations in a single etching step, 2 × 2 and 3 × 3 crossings achieve broadband transmission with low loss and ultralow crosstalk across 220 ...
