Metasurfaces control polarized light at will

For years, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have engineered metasurfaces to manipulate light based on its polarization state. That research has contributed to advances ...

Tunable 'metasurface' is akin to optical swiss army knife

MIT engineers and colleagues report important new advances on a tunable metasurface, or flat optical device patterned with nanoscale structures, that they compare to a Swiss army knife while its passive predecessor can be ...

Novel microscopy method provides look into future of cell biology

What if a microscope allowed us to explore the 3D microcosm of blood vessels, nerves, and cancer cells instantaneously in virtual reality? What if it could provide views from multiple directions in real time without physically ...

Light-emitting MXene quantum dots

In a new publication from Opto-Electronic Advances, researchers led by Professor Jeongyong Kim at the Department of Energy Science, Sungkyunkwan University, Suwon, Republic of Korea, review light-emitting MXene quantum dots.

Nanophotonics enhanced coverslip for phase imaging in biology

The ability to visualize transparent objects such as biological cells is of fundamental importance in biology and medical diagnostics. Conventional approaches to achieve this include phase-contrast microscopy and techniques ...

Researchers achieve 51.5dB nonreciprocal isolation

Chinese researchers achieved 51.5dB nonreciprocal isolation in the atomic ensemble, which is the highest isolation ratio in the non-magnetic nonreciprocal field. They discussed the quantum noise problem in nonreciprocal devices ...

New biosensor designed to detect toxins and more

A device from Los Alamos National Laboratory researchers is not quite the Star Trek "tricorder" medical scanner, but it's a step in the right direction. The Portable EnGineered Analytic Sensor with aUtomated Sampling (PEGASUS) ...
