摘要
An apparatus and method for automatically analyzing and controlling intensity of a train of high speed, high power multi-level optical pulses. The invention includes an optical pulse generator for generating the train of high speed, high power, multi-level optical pulses, wherein the optical pulse generator provides a low optical intensity level and a medium optical intensity level and a high optical intensity level. A photodetector is optically coupled with the optical pulse generator for generating a train of electrical pulses having amplitude levels in response to optical intensity levels of the train of optical pulses. At least one reference is employed, wherein an analyzer electrically coupled with the reference and the photodetector for analyzing the amplitude levels of the train of electrical pulses in comparison to the reference. A controller is electrically coupled with analyzer for generating a high correction signal based upon the analysis of the amplitude levels.
