Novel design may boost efficiency of on-chip frequency combs

On the cover of the Pink Floyd album Dark Side of the Moon, a prism splits a ray of light into all the colors of the rainbow. This multicolored medley, which owes its emergence to the fact that light travels as a wave, is ...

Scientists realize noiseless photon-echo protocol

Prof. LI Chuanfeng and Prof. Zhou Zongquan from University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) innovatively raised and realized noiseless photon echo (NLPE) protocol. The research ...

Researchers model new method of generating gamma-ray combs

Skoltech researchers used the resources of the university's Zhores supercomputer to study a new method of generating gamma-ray combs for nuclear and X-ray photonics and spectroscopy of new materials. The paper was published ...

'Agricomb' measures multiple gas emissions from... cows

After the optical frequency comb made its debut as a ruler for light, spinoffs followed, including the astrocomb to measure starlight and a radar-like comb system to detect natural gas leaks. And now, researchers have unveiled ...
