In optics, when a collection of nonlinear processes act together on a pump beam, the resulting spectral broadening of the original pump beam gives rise to a supercontinuum. Supercontinuum sources for optical coherence tomography ...
Bay Area scientists have captured the real-time electrical activity of a beating heart, using a sheet of graphene to record an optical image—almost like a video camera—of the faint electric fields generated by the rhythmic ...

Astronomers have reported the discovery of a new galactic supernova remnant (SNR) in the Cepheus constellation. The newly detected SNR is relatively large and optically bright, but faint in radio and X-ray bands. The finding ...
High-capacity optical communication can be accomplished by multiplexing multiple light-carrying orbital angular momentum (OAM) channels. However, in turbulent environments, optical scattering and 'speckle patterns' occur ...
Optical coherence tomography (OCT) is a light-based imaging technique currently used in clinical diagnostics to examine organs in vivo. The technique uses interferometry; in which light reflected from an examined object combines ...

(Phys.org)—A team of researchers at Washington University in St. Louis has built a camera apparatus capable of capturing moving imagery of an optical Mach cone. In their paper published in the journal Science Advances, ...
To design the next generation of optical devices, ranging from efficient solar panels to LEDs to optical transistors, engineers will need a 3-dimensional image depicting how light interacts with these objects on the nanoscale.
