9. A system for communication, the system comprising:
an optoelectronic circuit comprising a directional coupler, a first photodetector, at least two transistors connected to the first photodetector, an optical delay, and a differential transimpedance amplifier (TIA), the optoelectronic circuit being operable to:
receive an input optical signal;
split the input optical signal into a first optical signal and a second optical signal via the directional coupler;
delay the first optical signal via the optical delay;
convert the delayed first optical signal to a first electrical signal using the first photodetector;
convert the second optical signal to a second electrical signal using a second photodetector with at least two transistors connected to the second photodetector and the differential TIA; and
sum the first and second electrical signals using the differential TIA.
