Laser &Photonics Reviews, EarlyView.Maximized emission enhancement is experimentally achieved using critical coupling in Brillouin zone folding metasurfaces. Maximized enhancements of polarized and unpolarized emissions from quantum dot‐coated dielectric metasurfaces are demonstrated in the normal direction.

Reflections on the Spatial Exponential Growth of Electromagnetic Quasinormal Modes
Laser &Photonics Reviews, EarlyView.Quasinormal modes (QNMs) offer a robust framework for understanding the physics of resonators. However, conceptual challenges arise in regions distant from resonators, where QNM fields exponentially grow. This growth is not unphysical, but gives rise to counterintuitive effects, which is explained by examining fundamentals of non‐Hermitian systems ...

High‐Speed Multimode Fiber Imaging Using Binary‐Modulated Silicon Photonics Optical Phased Array
Laser &Photonics Reviews, EarlyView.A multimode fiber imaging system at 500 frames per second is experimentally demonstrated. It is enabled by a p‐i‐n diode‐based silicon photonics optical phased array. To simplify the electrical driving of p‐i‐n diodes, a binary modulation method with a costumed‐designed digital driver circuit is proposed. Reconstruction of each frame takes only 0.1 ms,

3D Dielectric Chiral Metamaterials Achieving Nondispersive Near‐Zero Ellipticity
Laser &Photonics Reviews, EarlyView.Broadband and high‐transmission‐efficiency optical activity (OA) is a critical functionality for numerous applications but is challenging to achieve. By engineering circularly polarized (CP) eigenstates in three‐dimensional (3D) dielectric helices, a 3D‐printed ceramic metamaterial is demonstrated for broadband OA with nondispersive near‐zero ...

Discrete Chiral Ballistic Polariton Laser
Laser &Photonics Reviews, EarlyView.Planar microcavities in the strong light–matter coupling regime exhibit exciton‐polariton modes with a strong chiral response toward circularly polarized light. This feature is exploited alongside inherent spin‐orbit coupling of cavity light to generate giant discrete optical vortices in polygonal arrays of exciton‐polariton condensates.
