Scientists have developed the first electrically pumped continuous-wave semiconductor laser composed exclusively of elements from the fourth group of the periodic table—the "silicon group.
Dr. Dan Buca, Group Leader, Forschungszentrum Jülich For the first time, researchers have demonstrated continuous-wave operation in an electrically pumped Group IV laser on silicon. Unlike ...
Leveraging the low-defectivity GaAs nano-ridge structures, the lasers integrate InGaAs multiple quantum wells as the optical gain region, embedded in an in-situ doped p-i-n diode and passivated with ...
