Avalanche photodiodes
2015/6/4
We report the first demonstration of a waveguide-integrated avalanche photodetector using Group-IV heterostructure materials. Such device achieved a responsivity of ~0.8A/W at unity gain and an impres...
Scientists at IBM have used nano-engineering techniques to make the world's fastest "avalanche photodetector". Such devices are used in telecommunications networks and the work is an important advance...
