Quantum Dots – The Resurrection?

After more than 30 years of research, and more than 10 years since the first field deployments, quantum dot (QD) based lasers and semiconductor optical amplifiers (SOAs) have recently begun generating strong interest. QDs offer unique properties and additional degrees of freedom in design compared to traditional quantum wells. They are being explored for use in various applications, and for monolithic integration into silicon photonics manufacturing platforms. Is this resurgence based upon improved quality of the quantum dots, or on fundamentally new properties? Is isolator-free on-chip silicon integration the "killer app"? Is this success transferable back to III/V substrates like InP or GaAs? Where further can quantum dots go in performance? Will CdSe, ZSe, or other colloidal quantum dots play a role?
