By using a Ge lateral p++/p+/n+/n++ junction waveguide photodiode integrated with a dual-stage Mach-Zehnder interferometric waveguide demultiplexer for 4-channel CWDM SMF network at O-band, the error-free receiving of the broadband optical QAM-OFDM data stream at 136 Gbit/s within 34 GBaud bandwidth is successfully demonstrated.
