Minimizing back reflection of high-speed Ge-on-Si PIN photodetectors with advanced Ge shaping techniques
We present advanced Ge shaping techniques for O-band Ge-on-Si photodetectors, achieving -36 dB optical return loss, ~60 GHz 3-dB EO bandwidth, 0.95 A/W responsivity, and average dark current below 30 nA.
