Researchers at Nichia Corporation have demonstrated green InGaN-based lasers grown on c-plane sapphire, with lifetimes capable of supporting commercial applications. The demonstration of green ...

Blue Light Emitting Diodes (LEDs) are semiconductor devices that emit blue light when activated. They are part of the visible LED spectrum and are used to produce blue light by utilizing specific ...

A semiconductor diode is a non-linear device whose most outstanding feature is the fact that, basically, current is only allowed to flow in one direction. The diode is built by joining together two ...

The UK says a new anti-missile laser for its aircraft defeated 100% of its targets in a live test. Officials said it faced off against multiple heat-seeking missiles launched simultaneously.

Abstract: 885 nm laser diode with high Al component AlGaAs barrier layers (HABLs) are designed and fabricated to mitigate carrier leakage. As the height of the potential barrier increases, the ...

SAN FRANCISCO--A start-up that a Nobel laureate co-founded plans to commercialize a nuclear fusion reactor using laser technology by around 2030. Shuji Nakamura, co-recipient of the 2014 Nobel ...

In a statement, officials said the laser downed 100% of its targets at the Vidsel Test Range in Sweden while facing "a range of infrared heat-seeking missiles being fired simultaneously." ...

Semiconductor lasers are excellent candidate of chaotic transceivers thanks to their easy-to-integrate structures and high chaos complexity, but still encounter a key challenge that the transmission ...
