Abstract
Methods and systems for current amplification to improve optical amplifier performance may include equalizing a current level indicative of input optical power to an optical amplifier with a current level indicative of an output optical power level of the optical amplifier. In this manner, a first bandwidth of an input log amp may be matched with a second bandwidth of an output log amp in a gain control loop circuit to improve overall transient gain accuracy of the optical amplifier, irrespective of the input optical power. In this manner, the optical amplifier may be enabled to operate at a defined gain level even in the presence of transients in the input signal.
