| Abstract(in English) | We have investigated polarized optical gain of columnar quantum dots by using variable stripe length method. The columnar QDs were grown by closely stacking the Stranski-Krastanow-mode InAs-island layers. The aspect ratio of the QD can be controlled by changing in the stacking layer number (SLN). The optical gain sensitively depends on the SLN. With increasing the SLN, the TM-sensitive optical gain has been demonstrated. Furthermore, we obtained almost polarization insensitive optical gain for the sample with seven staking layers. |
