1. A method for communication, the method comprising:

  • in an optoelectronic receiver comprising a directional coupler, first and second photodetectors, first and second transimpedance amplifiers (TIAs), and a gain stage;

    receiving an input optical signal;

    splitting the input optical signal into first and second optical signals using the directional coupler;

    generating a first electrical current from the first optical signal using a first photodetector;

    generating a first voltage from the first electrical current using the first TIA;

    communicating the first voltage to a first input of the gain stage;

    generating a second electrical current from the second optical signal using the second photodetector;

    generating a second voltage from the first electrical signal using the second TIA;

    communicating the second voltage to a second input of the gain stage; and

    generating a differential output voltage from the first and second voltages using the gain stage.
