Scientists from China have developed high-performance colloidal quantum-dot (CQD)  surface-emitting laser array based on ...
Now, it appears that after two decades of development, a semiconductor laser design that meets these needs has finally arrived. Welcome to the photonic-crystal surface-emitting laser (PCSEL).
“Compared to photonic-crystal surface-emitting lasers, even the best conventional ... which will be key to commercialisation,” he says, “as well as working on highly robust designs, checking ...
