Luxtera's design eliminates the need to use expensive group iii-v compounds, such as gallium arsenide (GaAs) and indium phosphate (InP), in the semiconductors.

Luxtera的设计消除了使用昂贵的III - V化合物半导体材料(如砷化镓和磷化铟)的必要。

The trick is to tune the crystal, by modifying the details of pattern, so that as much of the emitted energy as possible is at the frequency most efficiently captured by indium gallium arsenide.

The other, which faces a specialised type of solar cell made of a material called indium gallium arsenide, is sculpted into a structure called a photonic crystal that causes it to emit infra-red radiation selectively at the frequency best absorbed by the cell.

Many optical components are typically constructed using materials such as gallium arsenide and indium phosphide.
