| Abstract(in English) | We developed a growth technique of InAs QD on InP(001) substrate by using vicinal surface of (001) and As_2 fulux. Using this structure, we successfully fabricated a highly stacked InAs QD laser. A stack of 30 InAs QD layers and InGaAlAs spacer layers were grown for an active region with a strain-compensation technique. This QD laser shows lasing at 1576 nm with a threshold current of 1037 mA at room temperature. The lasing wavelength was almost same as the peak wavelength of QD ground levels in photoluminescence. Therefore, this lasing occurs at QD ground levels, which result from the large optical gain of the highly stacked QDs.. |
