The first topological Dirac-vortex microcavity lasers on silicon are experimentally realized. Operating under room-temperature continuous-wave conditions, these lasers mark an important step toward integrating topological lasers with CMOS-compatible optoelectronic systems.
We review the two decades of tilted pulse front pumping, and suggest its applications to new materials and laser sources, emphasizing its potential with semiconductors and organic crystals for promising advancements.
Integration of curved GaAs metagratings onto VCSELs enables a compact on-chip illumination solution for high-contrast microscopy, making it a versatile choice for light sources in lab-on-a-chip devices.
We unlock the height as accessible parameter of all-dielectric metasurfaces, allowing polarization-selective interaction of their high-Q eigenstates with light of different helicity and promoting ultra-narrow maximally chiral optical resonances.
Significant improvement of quantum efficiency and thermal stability of NIR-emitting Ca3Y2-2x(ZnZr)xGe3O12:Cr was achieved by chemical unit cosubstitution, benefiting from valence reduction of Cr4+ to Cr3+ and reconstructed rigid crystal structure.
The study introduces a novel approach to information encoding using 2D random wrinkles PUFs in a 3D framework, utilizing polarization manipulation and data extracting functions to enhance security in authentication systems.
