Scientists find a theoretical optical device may have uses in quantum computing.

Silicon-based system offers smaller, cheaper alternative to other “broadband” filters; could improve a variety of photonic devices.

Reducing the wavelength of light could allow it to be absorbed or emitted by a semiconductor, study suggests.

Neural network could expedite complex physics simulations.

Bandage is threaded with photonic fibers that change color to signal pressure level.

Technique would allow addition of optical communication components to existing chips with little modification of their designs.

Startup’s optoelectronic chips could reduce energy usage by up to 50 percent in data centers while increasing computing speeds.
