Photonic resonances provide an easy on-chip classification method for nanoplastic particles.

Terahertz technology has the potential to push the speed limit of future opto-electronic applications, but the large free-space wavelength of terahertz light hinders nanoscale device implementation. Now, the confinement of terahertz light to the nanometre scale is demonstrated using phonon polaritons in hafnium-based van der Waals crystals.

Vortex 6.0: Milestone technology for all-on-chip integrated reconfigurable structured light platform.

Combining a low-coherence source with silicon nitride ring resonators featuring normal group velocity dispersion enables electrically pumped, high-power microcombs, providing on-chip power up to 158 mW and high-coherence comb lines with linewidths as narrow as 200 kHz.

This study demonstrates GHz-speed electro-optic modulation using ferroelectric nematic liquid crystals, offering dual-phase shifting, poling-free operation, low loss, and CMOS compatibility-enabling scalable hybrid silicon-organic photonics.

By employing a high spatial-resolved photoemission electron microscopy, we demonstrate near-field imaging and characterization of ultra-confined optical near fields in nanoslits with weak disturbance.

The high-contrast dielectric boundary between a gold–air hybrid structure and its sharp spatial features are exploited to provide the momentum required for the excitation of higher-order hyperbolic phonon polaritons.

Editor Summary-Interacting bosons in non-Hermitian lattices challenge conventional expectations by clustering collectively rather than dispersing. In this work the authors uncover a counter-intuitive “caging” effect where repulsive interactions-rather than spreading particles-work with non-Hermiticity to pin bosons at one edge, beyond what non-Hermiticity alone predicts.

Sonochemical exfoliation of synthesized bulk black phosphorus crystals provides a route to produce high-quality, narrow and clean black phosphorus nanoribbons for practical applications in electronic and optoelectronic fields.

The integration of a quantum emitter-embedded metasurface (QEMS) with a microelectromechanical system (MEMS)-actuated cavity enables ångstrom-level wavelength tuning and dynamic polarization-resolved emission. The platform provides a design paradigm for reconfigurable solid-state photon sources.
