Design ideas for making new optical devices borrow from supersymmetry, a candidate theory in particle physics.

An optomechanical system in which light and matter exchange roles promises new kinds of quantum states.

The sloshing of light between optical waveguides replicates the quantum-mechanical exchange between an atom and an electromagnetic mode.

The next generation of ultrahigh energy lasers will be able to produce extremely dense electron-positron plasmas and intense bursts of gamma rays, according to simulations, and both will lead to new types of experiments.

A waveguide’s dielectric properties could result in an effective gauge field for photons even though they have no charge.

Quantum interference of pairs of photons emitted by nitrogen-vacancy centers in diamond paves the way for entanglement of distant qubits.
