| Abstract(in English) | Semiconductor self-assembled quantum dots (QDs) that have zero-dimensional carrier confinement structure are predicted to have unique physical properties. And QDs are expected to increase the performance of various semiconductor optical devices such as the QD laser or LED. By using the semiconductor quantum well structure, only one dimension of the height can be controlled the quantum energy level, on the other hand, in the QDs structure, the three-dimensional control of the energy level is possible, and we can obtain the wide energy level control in the QDs structure. In this study, we have fabricated the novel wide wavelength emission QDs device by using arrayed waveguide structure grown by selective area growth and also by using the double-cap procedure during the QDs growth and changing the height of QDs layer by layer. The wide wavelength emission source can be applied, such as very wideband wavelength division multiplex (WDM) system, including the 1.55μm optical telecommunication wavelength, and the environmental gas detecting in the longer wavelength near the 2.0μm. |
