We obtain low-density charged InAs quantum dots with an emission wavelength below 1μm using a low InAs growth rate.The quantum dots have a bimodal size distribution with an emission wavelength of around 1340nm and 1000 nm, respectively. We observe the photoluminescence of the singly charged exciton in the modulation doped quantum dots in 77K.
