Bowers Article Open Access 14 Oct 2022 Formation and fluorescent mechanism of red emissive carbon dots from o-phenylenediamine and catechol system The fluorophore source of red emissive oPD&CAT system CDs is the 5,14-dihydroquinoxalino[2,3-b] phenazine (DHQP), formed in the initial reaction stage. Subsequently, the DHQP was connected with carbon core. The excited electrons of the molecular state can transfer into the energy level of CDs, which leads to UV excitation red emissive intensity decreased. Pengfei LiShanshan XueZaicheng Sun Article Open Access 13 Oct 2022 The complex Maxwell stress tensor theorem: The imaginary stress tensor and the reactive strength of orbital momentum. A novel scenery underlying electromagnetic optical forces The imaginary Maxwell stress tensor IMST and the reactive strength of orbital momentum ROM are established. It is shown that they universally produce reactive electromagnetic forces ILFs that counteract all currently observed time-averaged optical forces RLFs. Manuel Nieto-VesperinasXiaohao Xu Article Open Access 12 Oct 2022 Dissipative soliton generation and real-time dynamics in microresonator-filtered fiber lasers We theoretically and experimentally study soliton generation and real-time dynamics via time magnifier in microresonator-filtered fiber lasers, achieving self-starting, broad-bandwidth, high-efficiency, and low-noise soliton microcombs at ≥ 10 GHz.

Xinzhu XuShu JiaPeng Xi News & Views Open Access 10 Oct 2022 Ultracompact topological photonic switch based on valley-vortex-enhanced high-efficiency phase shift An ultracompact 1 × 2 thermo-optic topological switch is demonstrated by leveraging the high-efficiency phase-shifting property and the sharp-turn feature of the topological waveguides. Hongwei WangGuojing TangYikai Su Article Open Access 10 Oct 2022 InGaN micro-light-emitting diodes monolithically grown on Si: achieving ultra-stable operation through polarization and strain engineering Micro-light-emitting diodes (µLED) with bright, ultra-stable green emissions are monolithically achieved on Si substrate. The quantum-confined Stark effect is screened by introducing polarization doping in the shell.
