A high-saturation-current, backside-illuminated In0.53Ga 0.47As photo-diode with a partially depleted absorber has been fabricated and tested. The 1 dB small-signal compression current was 199 mA at 1 GHz for a 100 μm diameter photodiode. The 1 dB large-signal compression current was 24 mA at 48 GHz for an 8 μm-diameter photodiode. The responsivity was 0.6 A/W at 1.55 μm.
