Electronically programmable photonic molecule

Physical systems with discrete energy levels are ubiquitous in nature and form fundamental building blocks of quantum technology. Artificial atom-like and molecule-like systems were previously demonstrated to regulate light ...

Engineers efficiently 'mix' light at the nanoscale

The race to make computer components smaller and faster and use less power is pushing the limits of the properties of electrons in a material. Photonic systems could eventually replace electronic ones, but the fundamentals ...

Two photons strongly coupled by glass fiber

Usually, light waves do not interact with each other. Coupling of photons with other photons is only possible with the help of special materials and very intense light. Scientists in Vienna have now created the strongest ...

Spirals of light may lead to better electronics

(Phys.org) —A group of researchers at the California Institute of Technology (Caltech) has created the optical equivalent of a tuning fork—a device that can help steady the electrical currents needed to power high-end ...

MIT researchers build an all-optical transistor

Optical computing—using light rather than electricity to perform calculations—could pay dividends for both conventional computers and quantum computers, largely hypothetical devices that could perform some types of computations ...

'Building block' of quanutm networks created

(Phys.org)—A proof-of-concept device that could pave the way for on-chip optical quantum networks has been created by a group of researchers from the US.
