Quantum dot laser
A semiconductor laser whose gain region uses self-assembled nanoscale islands rather than quantum wells, giving low threshold current, high temperature stability and strong tolerance to crystal defects.

Notes
Defect tolerance makes quantum dots the leading route to lasers grown directly on silicon despite the lattice mismatch.
