Long‐Range Exciton Energy Transfer in Two‐Dimensional Materials
Laser &Photonics Reviews, EarlyView.This review highlights recent advances in long‐range exciton energy transfer within planar 2D‐material architectures. It emphasizes the emergence of self‐hybridized excitonpolaritons, exciton coupling to surface plasmon polaritons and plasmonic lattices, and the role of dipoledipole transfer pathways in enabling efficient nanoscale energy transport ...

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 ...

Photonic Systolic Array for All‐Optical Matrix–Matrix Multiplication
Laser &Photonics Reviews, EarlyView.A photonic systolic array is introduced, offering extreme parallelism in matrix‐matrix multiplication based on the synchronized movement of optical pulses along a crossbar array. Optical pulses traveling in perpendicular directions meet at freeform‐designed multiply‐accumulate units, each tailored to generate two signals whose intensity difference ...

Laser &Photonics Reviews, EarlyView.This study demonstrates uniform, durable non‐iridescent structural coloration using polystyrene nanoparticles randomly embedded in a thick sodium silicate with absorptive additives. By suppressing the effects of the structure factor and multiple scattering, this approach achieves uniform coloration from the backscattering.

Monolithic Integration of ScAlN Modulators on Silicon‐On‐Insulator Platform
Laser &Photonics Reviews, EarlyView.Monolithic integration of scandium‐doped aluminum nitride (ScAlN) modulators on a silicon‐on‐insulator platform is reported. A multilayer electrode design enhances RF‐optical field overlap, enabling direct access to the diagonal electro‐optic coefficient and improved modulation efficiency.
