Linear mode avalanche photodiode without excess noise

摘要

The linear mode avalanche photodiode produces light gain of more than 1000 times amplification, while sensing the light by being configured to produce an excess noise figure less than three times the thermal noise present at a temperature above non cryogenic temperature due to amplification gain Output current.This linear mode avalanche photodiodeCollision ionization is suppressed for the first carrier of linear mode avalanche photodiodeOn the other handFor a second carrier1) increasing impact ionization2) substantially maintaining collision ionizationBy using a superlattice structure matched to achieve at least one of suppressing collision ionization at a lower degreeDetects one or more photons in light.The first carrier whose collision ionization is suppressed is either I or II) and the second carrier is electron or hole.
