Abstract :
We present microwave characteristics of evanescently coupled Ge waveguide photodetectors grown on Si rib waveguides. At 1 GHz and 40 mA of photocurrent, an OIP3 of 36.49 dBm is measured. Additionally, the maximum RF power extracted at 1 GHz is 14.35 dBm at 60 mA of photocurrent and 8 V reverse bias.
