Mode control is essential for optical communications and data processing technologies. Whether it's connections and switches in data transmission lines or some sort of non-reciprocal device for optical circuits, the ability ...
One nanotube could be great for electronics applications, but there's new evidence that two could be tops.
A quantum sensor could give Soldiers a way to detect communication signals over the entire radio frequency spectrum, from 0 to 100 GHz, said researchers from the Army.
Near-infrared spectroscopy provides absorption spectrum unique to substances so that discrimination of gas species becomes possible. Miniaturization of spectrometers is thus required to realize compact gas sensors for monitoring ...
For the first time, researchers have used an advanced analytical technique known as dual-comb spectroscopy to rapidly acquire extremely detailed hyperspectral images. By acquiring a full spectrum of information for each pixel ...
For 20 years, researchers have studied how light rotates around a longitudinal axis parallel to the direction light travels. But could it move in other ways? After two years of research, and thanks to a sabbatical, University ...
Optical manipulation on the nano-scale, or nanophotonics, has become a critical research area, as researchers seek ways to meet the ever-increasing demand for information processing and communications. The ability to control ...
Applying bound states in the continuum (BICs) in photonic integrated circuits enables low-loss light guidance and routing in low-refractive-index waveguides on high-refractive-index substrates. Here, we demonstrate high-quality ...
Scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory are exceptional in many respects. Working in collaboration with the Imperial College London, for example, they have conducted research on a phenomenon ...
Fiber-optic strain sensing is known for its ability to monitor large areas. However, most types of fiber-optic strain sensors require spectrum analysis instruments, which drastically increases the overall cost of sensor systems. ...
