Silicon photonics revolutionizes data transmission with faster, more efficient lasers integrated on silicon wafers.

Lasers are great for heating things up, whether you need to do it quickly, hit a precise target, or do it from a distance.

The most optimal material for solid-state lasers in photonics is gallium-arsenide (GaAs), but due to ... Naturally, it’s far easier and cheaper if a GaAs laser can be grown directly on the ...

The first official LED was created in 1927 by Russian inventor ... of experimenting with materials such as silicon carbide, gallium arsenide, gallium antimonide, indium phosphide, and silicon ...

Most crucially, however, the LED is a vital link between electronics ... the 1962 reports of laser action in gallium-arsenide-based diodes were underpinned by such spectral measurements.

Since the early 1970s, scientists have been promoting gallium arsenide as a faster, more efficient substrate material than silicon for making integrated-circuit chips. However, the vast majority of ...

The history of the blue-light laser diode is closely linked to that of the blue LED. Early commercial semiconductor light sources were made using semiconductor compounds gallium arsenide or ...

In 2001, Motorola developed a technique that places a spongy layer between gallium arsenide and silicon on the same wafer. Combining these two materials yields a higher-speed product at a lower cost.
