All-silicon laser makes its debut Scientists at Intel have made the first all-silicon laser. The breakthrough could lead to the development of silicon chips that can be used in both electronic and photonic applications. Existing photonic devices are made from expensive compound semiconductor materials such as gallium arsenide or indium phosphide (H Rong et al. 2005 Nature to be published). Silicon dominates the microelectronics industry but it is not used in photonic applications because it does not emit light inefficiently.
