1. A computer implemented method for centralized automatic bias control for a plurality of modulators, comprising:

  • coupling, using a coupler, output of each of the plurality of modulators to generate a combined modulator output;

    inserting, using a pilot insertion device, a pilot tone into each of the plurality of modulators, wherein a different pilot tone frequency is inserted for each of the plurality of modulators;

    monitoring, using a monitoring device, power (Pt) of each inserted pilot tone over time to determine whether a current modulator bias is optimal, based on a threshold condition, for each of the plurality of modulators;

    adjusting, using an adjuster device, the current modulator bias determined to be sub-optimal for each of the plurality of modulators; and

    iterating the monitoring and adjusting until the threshold condition has been met.
