A high-speed and high-output-peak-voltage edge-illuminated refracting-facet
photodiode has been developed by employing a thin absorption layer. The fa
bricated RFPD shows a responsivity as high as 0.69A/W even with an absorpti
on layer as thin as 0.43 mu m, a maximum 3dB bandwidth of 66GHz, and a high
-output peak voltage of > 2.5V.
