Monostable-Bistable Threshold Logic Elements In A Fully Complementary Optical Receiver Circuit For High Frequency Applications

A fully complementary optical receiver design is presented utilizing two Monostable-Bistable Threshold Logic Elements, consisting of four Resonant Tunneling Diodes and a pin-photodetector in one circuitry. By complementary on and off switching of the two Monostable-Bistable Logic Elements it is possible to double the sampling rate of the optically generated photocurrent. Measurements on fabricated circuits have shown functionality up to 13.2 Gbit/s.
