As great as silicon is for semiconductor applications, it has one weakness in that using it for lasers isn’t very practical. Never say never though, as it turns out that you can now grow ...

Most of these lasers are made from rigid, brittle, semiconductor crystals such as gallium arsenide. Organic semiconductors are a newer class of electronic material. Flexible, based on carbon and ...

T oday, silicon photonic circuits connect server racks and play key roles in chemical sensors, biosensors, and LIDAR for self-driving cars. But making these devices work requires ...

Silicon photonics uses light to transmit data instead of relying on electrical signals, but since silicon itself can’t ...

For many years, semiconductor lasers, tiny chips emitting light ... To date, most efforts have focussed on making PCSELs from the gallium arsenide semiconductor system, which operates at a ...

Another major advantage is that gallium arsenide can be doped in such way that it emits light, which makes it useful for lasers and light-emitting ...

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 ...

An alloy of gallium ... gallium arsenide and silicon on the same wafer. Combining these two materials yields a higher-speed product at a lower cost. See gallium nitride and III-V semiconductor.

A semiconductor-based laser used to generate analog signals ... semiconductors used in laser diodes are compounds based on gallium arsenide (750 to 900 nm in the infrared), indium gallium arsenide ...

A Belgian-Canadian research team claims to have found a way to develop gallium arsenide (GaAs) solar cells at a lower cost while maintaining high power conversion efficiencies. The scientists said ...
