Photon-cascade correlation spectroscopy enables peering into the quantum realm: Creating an image-in-time of photons reveals whether they tend to travel together or not, which...

Higher-order topological insulators (HOTIs) have a unique surface signature that determines how they reflect light—and it can be used to experimentally confirm the existence of...

A breathing soliton laser helps researchers discover modulated subharmonics, a new state of nonlinear systems, which contains both synchronized and desynchronized signals.

Purdue University researchers merge optical engineering with cutting-edge computational imaging techniques—a spinning metasurface stack breaks thermal light down into its spectral...

Researchers in Japan unveil an optical technique to generate gigahertz repetition pulses with individual colors and shapes—with potential ultrafast imaging and laser processing...

What happens when you replace linear optics with nonlinear optics for teleportation? You get a new quantum transport method that doesn’t require a bunch of extra photons.
