A research team in Korea has experimentally demonstrated, for the first time in the world, a nonlinear wave phenomenon that changes its frequency—either rising or falling—depending on which direction ...

A team led by Prof. GUO Guangcan and Prof. ZOU Changling from the University of Science and Technology of China of the Chinese Academy of Sciences realized efficient frequency conversion in ...

Voltage-to-frequency converter chips provide a signal frequency output as a function of an analog input voltage. A voltage-to-frequency converter chip is widely used for applications where a ...

In certain applications, like pH measurement based on electromagnetic field (EMF) changes in an electrochemical reaction, the change in voltage is very small and the voltage range varies with the ...

Nanowire (NW) lasers with the NW simultaneously acting as gain medium and optical cavity are attractive for miniaturized photonic integration systems, which have merits of ultracompact footprint, easy ...
