If you’re in the market for a new set of hi-fi speakers or studio monitors, you might have come across the term ‘waveguide’ before. You might’ve seen a photo or illustration in marketing materials ...

Researchers have developed a new way to control and manipulate optical signals by embedding a liquid crystal layer into waveguides created with direct laser writing. The new devices enable ...

Waveguide-enhanced Raman spectroscopy (WERS) exploits the electromagnetic enhancement that can be achieved at the surface of suitably designed waveguides to enhance Raman intensity. In this Primer, ...

Comprised of judiciously engineered microscopic photonic structures with subwavelength features, the concept of metasurface and metamaterials have proven fruitful results in the realm of meta-optics.
