Abstract
A system for correcting phase noise and/or drift includes an optical signal module, at least one optical transport module, at least one sampling module, an analysis circuit, and a measurement instrument. The optical signal module is capable of outputting a modulated optical signal. The at least one optical signal transport module includes a beam splitter capable of separating at least backward travelling waves based on polarization. The at least one optical signal transport module further includes a partially reflecting reflector capable of creating a backward travelling wave, the partially reflecting reflector being located after the polarization rotator. The at least one sampling module is configured to receive and sample the backward travelling wave created by the partially reflecting reflector and forwarded to the at least one sampling module by the beam splitter, thereby obtaining an electric correction signal. The analysis circuit is configured to correct measurement data obtained by the measurement instrument based on the electric correction signal.
