Metal‐Insulator‐Semiconductor Structure‐Based InGaN/GaN Micro‐Light‐Emitting Devices with Superior External Quantum Efficiency

open access: yesLaser &Photonics Reviews, EarlyView.
Micro‐LEDs with a novel metal‐insulator‐semiconductor (MIS) sidewall structure enable bias control of surface recombination and efficiency. Applying a positive sidewall voltage improves more than 50% EQE at low current density and achieves a record‐high 53.9% EQE.

Monolayer J‐Aggregate Crystals Strong Coupling with an All‐Dielectric Metasurface for Photonic Properties Modification

open access: yesLaser &Photonics Reviews, EarlyView.
The monolayer J‐aggregate PTCDI‐C13, grown on thin hBN, is transferred to an all‐dielectric metasurface to achieve strong coupling between optical modes (GMRs and qBICs) and Frenkel excitons. With low losses in both microcavities and excitons, a Rabi splitting of 78 meV is observed in both reflectance and photoluminescence k‐space maps, enabling ...

Enhanced Dichroic Coloration Through Void‐Particle Induced Interference in Randomly Distributed Cu2O Octahedrons on Glass Substrate

open access: yesLaser &Photonics Reviews, EarlyView.
In randomly distributed Cu2O octahedron particles on a glass substrate, the absence of particles in certain areas generates a distinct “void‐particle induced interference” phenomenon. This effect results in notable reflection and transmission dichroism, characterized by two reflection peaks within the visible spectrum, but only a single transmission ...

Carrier Transport in Electrically‐Driven Photonic Crystal Membrane Lasers

open access: yesLaser &Photonics Reviews, EarlyView.
A model to study carrier transport in photonic crystal lasers with a buried heterostructure active region and a lateral current injection scheme is presented. The model identifies unconventional leakage paths which explain low injection efficiencies and enhanced recombination at the p‐doping interface observed experimentally.
