Quantum fluctuations found hidden beneath classical optical signals in polaritons

When optical materials (molecules or solid-state semiconductors) are embedded in tiny photonic boxes, known as optical ...

Sparks between microscopic bubbles could explain the ghostly, glowing will-o’-the-wisps, study finds

Flashes of microlightning between microscopic bubbles of methane in water may ignite the eerie blue flames of will-o’-the wisps, new research suggests.

Programmable optical chip merges photons to change color

Cornell researchers have built a programmable optical chip that can change the color of light by merging photons, without ...
