Research Abstract |
Three-dimensionally controlled quantum dot(QD) has aδ-function type density of states, which realizes high-performance devices. In particular, self-assembled InAs/GaAs QDs grown by utilizing the Stranski-Ktrastanov mode are suitable for laser and optical relay devices and are expected to realize polarization-insensitive operation, broad-band operation, and ultrafast response simultaneously. We developed a precisely controlled stacking technique of InAs/GaAs QDs exhibiting the one-dimensional properties. In particular, we fabricated semiconductor amplifiers including the stacked InAs/GaAs QDs and demonstrated the control of the polarization insensitivity.
