We propose a PIN photodiode combining high responsivity, fast drift times and low junction capacitance in BiCMOS technology. This fast PIN photodiode allows the design of fast optoelectronic integrated circuits (OEIC) for many advanced applications in optical sensing, optical data transmission and optical storage systems. Because of the low capacitance of 0.0105fF/ μm2 it is possible to design fast OEICs with large-area photodetectors. The proposed optical receiver applying a PIN photodiode with a diameter of 500 μm and a capacitance of only 2pF attains a -3dB bandwidth of 220MHz, which corresponds to a maximum data rate of 300Mbit/s.
