Germanium Tin Laser Could Increase Processing Speed of Computer Chips

Tuesday, February 7, 2017 - 09:01 in Physics & Chemistry

A multi-institutional team of researchers, led by University of Arkansas engineering professor Shui-Qing "Fisher" Yu and a leading semiconductor equipment manufacturer, have fabricated an "optically pumped" laser made of the alloy germanium tin grown on silicon substrates. The augmented material could lead to the development of fully integrated silicon photonics, including both circuits and lasers, and thus faster micro-processing speed at much lower cost.
