Low-voltage waveguide Ge APD based high sensitivity 10Gb/s Si photonic receiver
We demonstrate low-voltage Ge waveguide avalanche photodetectors (APDs) with gain-bandwidth product over 100GHz. A 5.8dB avalanche sensitivity improvement (1×10-12 bit error ratio at 10Gb/s) is obtained for the wire-bonded optical receiver at -5.9V APD bias.
