Reconfigurable Giant Nonreciprocity at Near‐Normal Incidence via Phase‐Change Magneto‐Optical Metagratings

Laser &Photonics Reviews, Volume 20, Issue 18, 18 September 2026.
A phase‐change magneto‐optical metagrating combines GST switching with InAs guided‐mode resonances to achieve strong nonreciprocal absorption contrast near normal incidence. A static magnetic bias creates direction‐dependent resonant splitting, while GST crystallization quenches and latches the response.

Topotactic Nitridation Enabled Core–Shell La4Ti3(O,N)12@LaTiO2N for Efficient Photoelectrochemical Water Splitting

Small, Volume 22, Issue 49, 1 September 2026.
Topotactic nitridation of (111)‐plane layered perovskite La4Ti3O12 proceeds through a persistent 2D layered oxynitride La4Ti3(O,N)12, enabling formation of a core–shell La4Ti3(O,N)12@LaTiO2N heterostructure before full conversion into 3D perovskite LaTiO2N.

Full polarization control of photons with evanescent wave coupling in the ultra subwavelength gap of photonic molecules

Light: Science & Applications
Polarization of photons plays a key role in quantum optics and light-matter interactions, however, it is difficult to control in nanosystems since the eigenstate of a nanophotonic cavity is usually fixed and linearly polarized.
