Abstract
We present a vertical-illumination-type 100% Ge-on-Si photodetector with the quantum efficiencies up to of 75.2% at λ~1.55 μm and 96.4% at λ~1.31 μm. The 10 Gbps photoreceiver with a fabricated 90 μm-diameter Ge photodetector exhibits the sensitivity of -18.5 dBm at a BER of 10-12 for λ~1.55 μm, which is comparable to that of III-V counterpart.
