Laser &Photonics Reviews, EarlyView.Nonlinear orbital angular momentum (OAM) manipulation is crucial for fundamental physics and information technologies. An integrated lithium niobate platform combining Bragg diffraction and birefringent phase matching asymmetrically generates and controls second‐harmonic OAM beams, achieving a normalized conversion efficiency of 10−2 W−1 and supports a

Laser &Photonics Reviews, EarlyView.In this work, we investigated the dynamic retinal pathology of glaucoma from onset to late stages through longitudinal in vivo high‐resolution imaging in a silicone oil‐induced ocular hypertension (SOHU) glaucoma mouse model. We developed an optimized adaptive optics two‐photon excitation fluorescence microscopy (AO‐TPEFM) technique for morphological ...

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 ...

Reversible Thermal Tuning of High‐Q Non‐Local Lithium Niobate Metasurfaces
Laser &Photonics Reviews, EarlyView.Introducing a polarization sensor using scattering in a short optical fiber and deep learning. The breakthrough lies in sparse sampling of the scattered light and single‐photon sensitivity. The all‐fiber sensor achieves unprecedented accuracy, speed, resolution, and stability.
