Laser &Photonics Reviews, EarlyView.Te@Se core–shell heterojunction quantum dots (QDs) are synthesized by a two‐step strategy via combining liquid‐phase exfoliation and epitaxial growth. As active materials in photoelectrochemical photodetectors, Te@Se QDs exhibit excellent photo‐response performance in low‐concentration electrolytes and deionized water.

Comb‐Driven Coherent Optical Transmitter for Scalable DWDM Interconnects
Laser &Photonics Reviews, EarlyView.A comb‐driven coherent optical transmitter on a Si/SiN platform enables scalable DWDM interconnects by integrating ultra‐compact microring‐assisted modulators and interleavers. High‐baud coherent signaling achieves 400 Gb/s per wavelength and >$>$1 Tb/s multi‐channel transmission, with projected >$>$10 Tb/s per fiber, offering a path toward energy ...

Influence of a tilted cavity on quantum-dot optoelectronic active devices
, 2009 Quantum-dot laser diodes (QD-LDs) with a Fabry-Perot cavity and quantum-dot semiconductor optical amplifiers (QD-SOAs) with 7° tilted cavity were fabricated. The influence of a tilted cavity on optoelectronic active devices was also investigated. For the

Small, EarlyView.Single‐source chloride doping of ZnMgO electron‐transport layers (ETLs) intrinsically suppresses oxygen‐vacancy traps, eliminating storage‐driven positive aging in quantum dot light‐emitting diodes. Devices deliver day‐0 peak external quantum efficiency and longer operational lifetimes, while transport and interfacial photoluminescence remain time ...

Electrically Tunable Tunneling and Spectral Response in WSe2/h‐BN/CdSe/Graphene Heterostructure
Small, EarlyView.In the WSe2/h‐BN/CdSe quantum dot/graphene heterostructure, the graphene voltage dynamically tunes the tunneling barrier and energy alignment across the h‐BN layer. The bias‐dependent Fermi‐level alignment enhances the tunneling density of states, leading to efficient extraction of photo‐excited electrons from QDs into WSe2 and graphene.

Quantum-dot superluminescent diode: A proposal for an ultra-wide output spectrum
, 1999 We propose a novel superluminescent diode (SLD) with a quantum dot (QD) active layer, which should give a wider output spectrum than a conventional quantum well SLD.
