Abstract
In some embodiments, an apparatus includes an optical detector that can sample asynchronously an optical signal from an optical component that can be either an optical transmitter or an optical receiver. In such embodiments, the apparatus also includes a processor operatively coupled to the optical detector, where the processor can calculate a metric value of the optical signal without an extinction ratio of the optical signal being measured. The metric value is proportional to the extinction ratio of the optical signal. In such embodiments, the processor can define an error signal based on the metric value of the optical signal and the processor can send the error signal to the optical transmitter such that the optical transmitter modifies an output optical signal.
