1. An optical receiver system comprising:

  • a local oscillator configured to generate a laser signal to indicate a selection of one of a plurality of channels;

    a mixer configured to receive signals on the plurality of channels and to utilize the laser signal to distinguish the signal on the selected channel; and

    a processor configured to maximize a power level difference between the laser signal and at least one of the plurality of channels based on a total number of the plurality of channels by adjusting the power of the laser signal input to the mixer to limit a noise penalty in the receiver system.
