A distributed III-V-on-Si electroabsorption modulator based on an asymmetric segmented electrode has been developed the hybrid silicon platform for 1.3 μm transmission window. The measured modulation response shows a 2 dB drop at 67 GHz and extrapolated 3 bandwidth of 74 GHz. Large signal measurements show clearly open eye diagrams 50 Gb/s. An extinction ratio 9.6 back to 9.4 after 16 km were obtained with drive voltage 2.2 V.
