英文摘要
We have demonstrated 300 K lasing oscillation of the self-formed AlGaAs/GaAs laser diode on Si grown by metalorganic chemical vapor deposition for the first time. The AlGaAs/GaAs laser diodes with the self-formed GaAs islands active regions on Si substrates showed the threshold current of 260 mA,the threshold current density of 5.4 kA/cm^2 and the lasing wavelength of 791 nm with the FWHM of 2.8 nm under pulsed condition at 300 K.The self-formed GaAs islands on Si grown by the droplet epitaxy exhibited a conical shape with heights of 8 nm and effective diameters of 300 nm. Compared with the conventional quantum well laser diode on Si, the self-formed laser diode on Si exhibited the improved reliability due to the reduction of the dislocation number in the active region.
