Минимизация погрешности измерения фазовых шумов узкополосного лазера c помощью интерферометра Маха-Цендера на основе волокна с сохранением поляризации

А scheme for measuring phase noise using a РМ-fiber based Mach-Zehnder interferometer is proposed. Two interference signals from orthogonally polarized waves are formed in the scheme, which subsequently are separated by a poiarization demultiplexer. This allows to avoid the influence of external noise on the measurement result. An algorithm is described for calculating phase noise and the effect of temperature instability is estimated. In order to assess the operability of the scheme and the signal processing algorithm, the comparison is made of the calculated values of the phase noise and the values specified in the simulation.
