InfoMat, EarlyView.Layer‐controlled two‐dimensional perylene‐derivative molecular crystals grow by van der Waals vapor‐phase epitaxy and show near‐unity photoluminescence quantum yields. In hybrid structures with TMDCs, the carrier relaxation can be tuned from charge transfer to Förster resonance energy transfer.

1 W Single‐Mode Large‐Area Edge‐Emitting Laser via Non‐Hermitian Spatial Mode Filtering
Laser &Photonics Reviews, EarlyView.We demonstrate a non‐Hermitian spatial mode filtering approach for achieving high‐power single‐mode operation in large‐area edge‐emitting laser diodes. By symmetrically coupling passive filter arrays to the main lasing waveguide, higher‐order transverse modes are effectively suppressed while preserving the fundamental mode.

Parallel Multi‐Target Detection for Quantum LiDAR
Laser &Photonics Reviews, EarlyView.Parallel multi‐target detection is achieved in quantum LiDAR with a single‐pixel quantum readout. Direction and distance information are extracted together, allowing multiple objects to be distinguished under noisy low‐light conditions and pointing to a new strategy for scan‐free quantum remote sensing.

A transverse loading technique to enhance the pressure measurement capability of fibre Bragg gratings [PDF]
, 2008 A fibre optic pressure sensor based on the application of a transverse load onto an epoxy-resin material embedded over a sub-section of a fibre Bragg grating (FBG) is presented.

Laser &Photonics Reviews, EarlyView.Chip‐based frequency combs are usually pumped from telecom wavelengths, far from the visible. This work instead pumps close to the visible with a Ti:sapphire laser ‐ the source behind the original optical frequency combs and now becoming chip‐integrable‐ and lets silicon‐nitride waveguides convert it into efficient, octave‐spanning visible‐to‐infrared ...

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.Micro‐transfer printing enables GaAs and InP gain materials to be integrated on a commercial silicon nitride photonic platform. The resulting chip supports O‐ and C‐band comb and single‐mode lasers, demonstrating a scalable route toward multi‐material, multi‐wavelength, and multifunctional integrated light sources.

Laser &Photonics Reviews, EarlyView.Electrically contacted circular Bragg grating resonators incorporating InGaAs quantum dots directly grown on silicon enable bright, telecom O‐band single‐photon emission with wide‐range electrical tuning. A record quantum‐confined Stark shift of 16 nm is combined with high photon extraction efficiency, excellent single‐photon purity > 99.9%, and robust
