We report the fabrication and characterization of high-speed germanium on silicon-on-insulator lateral PIN photodetectors. At an incident wavelength of 850 nm, 10 × 10-μm detectors with finger spacing S of 0.4 μm (0.6 μm) produced a - 3-dB bandwidth of 29 GHz (27 GHz at a bias voltage of - 1 V. The detectors with S = 0.6 μm had external quantum efficiency of 34% at 850 nm and 46% at 900 nm and dark current of 0.02 μA at - 1-V bias.
