3D digital holograms on smartphones

3D holograms, previously seen only in science fiction movies, may soon make their way to consumer technology. Until now, 3D holograms based on phase shifting holography method could be captured using a large, specialized ...

Color-sorting metalenses boost imaging sensitivity

Researchers have shown that newly designed pixel-scale metasurface lenses—flat surfaces that use nanostructures to manipulate light—can be used to make imaging sensors that are roughly three times more sensitive than ...

The highest amplification in tiny nanoscale devices

A team of researchers from the University of Florida, led by Dr. Philip Feng, in collaboration with Prof. Steven Shaw in Florida Institute of Technology, has now demonstrated extremely high-efficient mechanical signal amplification ...

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 ...

Engineers bend light to enhance wavelength conversion

Electrical engineers from the UCLA Samueli School of Engineering have developed a more efficient way of converting light from one wavelength to another, opening the door for improvements in the performance of imaging, sensing ...

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.
