KAUST

Here, I will talk about recent advances in the field of QD lasers with a focus on direct growth on Si. Si photonics has found widespread application, particularly for high volume applications and for co-integration with CMOS electronics. I will start with an overview of the field, followed with a summary of device performance and fundamental physics basis for the improved response.
