Researchers have developed a graded grating structure that can be scaled to dimensions compatible with light waves in both the terahertz and telecommunications portion of the spectrum. The achievement ...
In 1933 Peter Kapitza and Paul Dirac predicted that a standing light wave would act as a ‘light grating’ that could diffract electrons. But light interacts only weakly with electrons, and early ...
Optical microelectromechanical systems (MEMS) devices are driving the trend toward all-optical telecommunication networks. With the ability to directly manipulate an optical signal, MEMS have several ...
The watch exists to measure the length of time, and it is not thought that there are other uses for it. But,strontiumUltrahigh accuracy using atoms"Light grating" atomic clockIt seems that you can ...
Holographic 3D display completely avoids the side effects of the traditional 3D display, such as the dizziness and fatigue of viewers. Therefore, it has become the frontier and hotspot of the current ...
The observation was made possible by powerful modern lasers and highlights the wave and particle nature of matter. Herman Batelaan and colleagues at the University of Nebraska hope to exploit the ...
