In this paper a laser way for obtaining "whisker" of semiconductor GaAs is presented and the prospect of using new material is simply described.

Silicon, germanium and gallium arsenide are popular materials used in ICs and semi-conduct devices, while silicon is the most popular one.

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.
