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 ...
Researchers have developed a new imaging method that can capture images at speeds of up to 1.5 million frames per second using standard imaging sensors typically limited to 100 frames per second. This new technology will ...

Optoacoustic imaging powered by short bursts of continuous wave (CW) lasers can stimulate the emission of ultrasound waves inside an animal or in human subjects. The method can noninvasively capture blood flow and produce ...
Newton's third law dictates that forces between interacting particles are equal and opposite for closed systems. In a non-equilibrium environment, the third law can be defied, giving rise to "nonreciprocal" forces. Theoretically, ...
A recently developed technique known as light-sheet fluorescence microscopy has led to many biological discoveries by allowing researchers to create 3-D images of tissue, even live animal embryos, using fluorescent tags. ...
