This video explains how diodes function as directional components in electronic circuits. Diodes allow current to flow in ...

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 ...

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 ...

As part of a NEDO project, Osaka University and Shimadzu Corporation have developed two new types of RGB laser light source modules, including a world-class high-brightness model and an ...

Light-emitting diodes (LEDs) are so ubiquitous that it's easy to forget just how much society relies on these underappreciated technological wonders. Yet, the history of the LED goes back further than ...
