  • A method for configuring light-trapping devices promises better optical nanodevices by amplifying light and enhancing the emission efficiency of luminescent nanomaterials — without the need for complex technology upgrades.

  • The ability of structures called optical resonators to trap light is often limited by scattering of light off fabrication defects. A physical mechanism that suppresses this scattering has been reported that could lead to improved optical devices.

  • Control of chiral light is essential in numerous fields from biosensing to quantum optics. Here, authors demonstrate a universal method to tune chiral response with metasurfaces using the interplay of resonator and lattice symmetries, enabling flexible design platform for advanced applications.

  • The authors engineer a type of bound states in the continuum in diatomic dielectric metasurfaces, allowing for high-quality resonances with accessible enhanced fields. Metasurface microarrays are integrated with microfluidics on an imaging platform for real-time detection of biosamples, based on reconstructing spectral shift information.

  • Though laser action has been reported for optical bound states in the continuum (BIC) cavities with high quality factors, these BIC lasers lacked practical applicability. Here, the authors report an ultralow-threshold super-BIC laser featuring merged symmetry-protected and accidental BICs.

  • We demonstrate that voids in high-index dielectrics support localized resonant modes which are confined in air and thus do not suffer from the loss and dispersion of the host medium
