Patent ID: 7620329

Claim:
A closed loop optic signal control system comprising: a memory configured to store one or more target values; a driver configured to process an outgoing signal based on the one or more target values and one or more compensation signals, wherein the target values represent driver control values; an optic signal generator configured to generate an optic signal representative of the outgoing signal based on the one or more target values and one or more feedback values; a detector configured to monitor one or more aspects of the optic signal and generate the one or more feedback signals; one or more peak detectors configured to detect one or more peak values of the feedback signal, wherein the one or more peak values are utilized to generate the one or more compensation signals and the one or more peak values are detected to determine an extinction ratio and/or a slope efficiency of the optic signal; a comparator configured to compare the one or more peak values to a threshold value, and the generation of the one or more compensation signals is responsive to the comparison; and one or more junctions configured to combine, through addition or subtraction, the one or more compensation signals with the one or more target values to create one or more driver control values that control the driver.
