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 ...

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 ...

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 ...

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 ...

For most design engineers, study of waveguide technology ended when they got their last degree. The only time waveguide comes up is to use it as a last resort in applications such as millimeter-wave ...

In recent decades, augmented reality (AR) has evolved from a futuristic concept to a tangible and pervasive technology. AR enhances our perception and interaction with the environment by seamlessly ...

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 ...
