In this paper,we have demonstrated a high performance waveguide photodiode integrated diluted waveguide serving as a fibre-to-waveguide coupler to achieve high coupling efficiency.High responsivity (> 1 A/W),high saturation power (> 45 mA) in the static state and extremely low dark current density (0.04 pA/μm 2) with 3 dB bandwidth at 13.4 GHz have been achieved.
