Computers That Use Light Instead of Electricity? First Germanium Laser Created
Image via Wikipedia
MIT researchers have demonstrated the first laser built from germanium that can produce wavelengths of light useful for optical communication. It’s also the first germanium laser to operate at room temperature. Unlike the materials typically used in lasers, germanium is easy to incorporate into existing processes for manufacturing silicon chips. [...]
