      abstract     = {Over the last 30 years, group-IV semiconductors have been
                      intensely investigated in the quest for a fundamental direct
                      bandgap semiconductor that could yield the last missing
                      piece of the Si Photonics toolbox: a continuous-wave
                      Si-based laser. Along this path, it has been demonstrated
                      that the electronic band structure of the GeSn/SiGeSn
                      heterostructures can be tuned into a direct bandgap quantum
                      structure providing optical gain for lasing. In this paper,
                      we present a versatile electrically pumped, continuous-wave
                      laser emitting at a near-infrared wavelength of 2.32 µm
                      with a low threshold current of 4 mA. It is based on a
                      6-periods SiGeSn/GeSn multiple quantum-well heterostructure.
                      Operation of the micro-disk laser at liquid nitrogen
                      temperature is possible by changing to pulsed operation and
                      reducing the heat load. The demonstration of a
                      continuous-wave, electrically pumped, all-group-IV laser is
                      a major breakthrough towards a complete group-IV photonics
                      technology platform.},
