Laser &Photonics Reviews, EarlyView.Room‐temperature lower‐polariton‐like lasing is realized in an InGaN/GaN thin‐film ridge cavity with lateral distributed Bragg reflectors. Near‐field optical microscopy distinguishes the transverse side‐DBR‐confined mode from a longitudinal photon‐like mode, while simulations reproduce their spatial profiles.

Laser &Photonics Reviews, EarlyView.A zero‐dimensional perovskite‐inspired scintillator (Cs3Cu2I5) is developed as a high‐radiation‐resilient radionuclide analyzer capable of operating under extreme γ‐ray environments. Even after 200 kGy irradiation, the device fully restores its original spectroscopic performance through simple thermal annealing, demonstrating intrinsic defect ...
