Butt-Coupled III-V Photodetector Monolithically Integrated on SOI with data reception at 50 Gbps OOK

We demonstrate the first in-plane waveguide butt-coupled high-speed III-V p-i-n photodetector monolithically integrated on standard SOI and demonstrate data reception at 50 GBd using OOK and a 3 dB cut-off frequency approaching 70 GHz.
