Metasurfaces are two-dimensional (2D), nanoengineered surfaces that interact strongly with electromagnetic waves and can ...

Materials scientists can learn a lot about a sample material by shooting lasers at it. With nonlinear optical microscopy—a ...

With the rise of quantum computers, the security of our existing communication systems is at risk. Quantum computers will be ...

Instead of relying on switches or digital control, the light finds its own path through the system. This approach could transform data transmission, computing, and communications by making optical ...

USC engineers have developed an optical system that routes light autonomously using thermodynamic principles. Rather than ...

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

The work, reported in Nature Photonics, introduces a new way of routing light in nonlinear systems—meaning systems that do not require switches, external control, or digital addressing. Instead, light ...

A method for configuring light-trapping devices promises better optical nanodevices by amplifying light and enhancing the emission efficiency of luminescent nanomaterials — without the need for ...

Office workers toiling under eye-tiring fluorescent bulbs have hope for a brighter day. A company called Sunlight Direct is developing a hybrid solar lighting system that distributes daylight into ...

Much like the murky waters of the deep ocean, the unpredictable fluidity of Earth’s atmosphere can distort any light that ...
