A fiber optic differential interferometer achieves low phase noise of 9.5 × 10−8 rad/Hz1/2, highlighting its effective dynamic range of 106 dB.
We developed a fiber optic differential interferometer based on polarization multiplexing, achieving a phase noise as low as 9 . 5 × 10 − 8 rad/Hz 1 / 2 and a dynamic range of 106 dB.
