Abstract

A silicon/III-V material active layer heterointegrated vertical PIN waveguide photodiode was developed and realized by silicon MEMS process and plasma assisted direct bonding. The InGaAsP Multiple Quantum Well (MQW) was integrated onto a SOI platform with highly doped micro rib by O2/Ar plasma assisted bonding which greatly improves the electrical property between the heterointerface. The photon-electron conversion of the photodiode was successfully demonstrated. The waveguide photodiode shows around 50% quantum efficiency at 1550nm and TE polarization.
