320 Gbit/s error-free demultiplexing using ultrafast optical gate monolithically integrating a photodiode and electroabsorption modulator

A 320 Gbit/s error-free demultiplexing operation with a receiver sensitivity of −18 dBm using a monolithic optical gate integrating a uni-travelling-carrier photodiode and a travelling-wave electroabsorption modulator has been demonstrated. High on/off ratios of 14 dB for adjacent channels and 28 dB for the others have also been achieved.
