Tensile-strained Ge photodetector is realized on Si-substrate using novel SiSiGe compliant layer with two-step Ge-process. Monolithic integration of p-i-n detectors with low dark current (0.4 nA), responsivity (190 mA/W) and high speed (5 GHz) on Ge-CMOS platform is demonstrated, with Ge pMOSFET showing 2X Si hole mobility.
