Abstract

Silicon photonics attracted much attention in past decades, but it is challenging for silicon laser source because of its indirect bandgap. The long-wavelength InAs/GaAs quantum dot (QD) laser monolithically grown on Ge substrate has been reported. Promising performance was reported by solid source molecular beam epitaxy (MBE). In this paper, gas source MBE was tried for the growth of InAs QD lasers on Ge. InAs QD laser is demonstrated in continuous wave mode at room temperature, with wavelengths covering 1.0-1.3 microns. The lowest threshold current density was obtained as 48 A/cm2 with an output power of several tens of mW.
