An ultra-fast optoelectronic circuit, using resonant tunnelling diodes (RTDs) and a uni-travelling-carrier photodiode (UTC-PD) is proposed. At extremely low power consumption, the circuit can demulitiplex an ultra-fast optical data signal into an electrical data signal with a lower bit rate. The monolithically fabricated circuit demultiplexed an 80 Gbit/s optical signal into a 40 Gbit/s electrical signal at 7.75 mW.
