This video explains what a diode is and how it controls the direction of current in electronic circuits. Diodes allow current ...
Solid-state and gas lasers have followed largely divergent development paths. Gas lasers are based primarily on direct electrical discharge for pumping (energizing), while solid-state lasers are ...
A deep blue organic light-emitting diode (OLED) developed by researchers at Science Tokyo operates on just a single 1.5 V, ...
The 2014 Nobel Physics Prize was presented to three researchers, Professor Isamu Akasaki, Professor Hiroshi Amano and Professor Shuji Nakamura for the invention of an efficient blue light-emitting ...
Researchers in Japan have developed two types of RGB (Red, Green and Blue) laser light source modules using RGB visible light laser diode technology. As a result of an evaluation of these modules by ...
In 1962, when he was 33, the scientist Nick Holonyak, Jr., created the first practical visible light-emitting diode. At GE, they called it "the magic one." Someone actually wrote that on the back—here ...
