  • Narrow linewidth lasers at visible wavelengths are crucial for quantum and atomic applications. Here, a visible Brillouin-quadratic microlaser was demonstrated with sub-kHz linewidth in an on-chip dispersion engineered lithium niobate microresonator.

  • The fabrication of artificial crystals by reassembling monolayer semiconductors enables on-demand engineering of their excitonic properties. Here, the authors report an efficient stacking method to fabricate millimetre-scale van der Waals homo-/hetero-crystals, demonstrating enhanced monolayer-like photoluminescence emission and quadrupolar interlayer exciton emission.

  • Existing quorum sensing (QS) circuits are less sophisticated for regulating multiple sets of genes or operons. Here, the authors redesign the luxR-luxI intergenic sequence of the lux-type QS system and apply it to achieve diverse metabolic control in salicylic acid and 4-hydroxycoumarin biosynthesis in E. coli.

  • Implementing metal nanowires in photonic circuits is challenging due to lack of suitable manipulation techniques. Here, the authors present an earthworm-like peristaltic crawling motion mechanism, based on surface plasmons and surface acoustic waves, and show on-chip manipulations of single nanowires.
