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.

A new publication from Opto-Electronic Sciences; DOI 10.29026/oea.2025.240114, discusses an ultra-high-Q photonic crystal nanobeam cavity for etchless lithium niobate on insulator (LNOI) platform. In ...

As buzz grows ever louder over the future of quantum, researchers everywhere are working overtime to discover how best to unlock the promise of super-positioned, entangled, tunneling or otherwise ...

Electrically controlled silicon photonic devices use carbon nanotube heaters to modulate and filter terahertz waves on chip with stable performance, enabling compact tunable components for high ...

US researchers unveil nanowire waveguides in the current issue of Science. While nanowire devices that can emit light and detect photons are already available, nanowire waveguides have so far proved ...

Optical waveguides are structures that guide and confine light within a small cross-sectional area. In nanophotonic circuits, waveguides are typically fabricated using high-refractive-index materials ...

Millimeter-wave Radars used in modern cars for cruise control and collision avoidance are usually designed to work at ranges on the order of 100 meters or so. With some engineering nous, however, ...

Quantum dot (QD) lasers engineered to emit a second harmonic in the yellow-red range could be ideal for high-resolution spectroscopy, say researchers at the University of Dusseldorf and German firm ...
