Monolithic Germanium Tin on Si Avalanche Photodiodes
Justin Rudie, Sylvester Amoah, Xiaoxin Wang +8
We demonstrate monolithically grown germanium-tin (GeSn) on silicon avalanche photodiodes (APDs) for infrared light detection. A relatively thinner Ge buffer design was adopted to…

Electrically Injected mid-infrared GeSn laser on Si operating at 140 K
Sudip Acharya, Hryhorii Stanchu, Rajesh Kumar +6
Owing to its true direct bandgap and tunable bandgap energies,GeSn alloys are increasingly attractive as gain media for mid-IR lasers that can be monolithically integrated on Si. D…
