摘要
We have fabricated and studied injection lasers based on vertically coupled quantum dots (VECODs). VECODs are self-organized during successive deposition of several sheets of(In,Ga)As quantum dots separated by thin GaAs spacers. VECODs are introduced in the active region of a GaAs-AlGaAs GRIN SCH lasers. Increasing the number of periods (...更多
