40 Gbit/s optical gate using optical modulator driven by uni-travelling carrier photodiode

摘要

The authors propose a simple optical gate that uses an electroabsorption modulator driven by a high-speed and high-saturation output photodiode. The photodiode generates a 10 GHz short electrical pulse larger than 2 Vpp and directly drives the modulator. The optical gate demonstrates as 40 Gbit/s 4:1 demultiplexing operation.
