Optical fiber phase noise
WebApr 3, 2024 · In long fiber-optic coils, like those used in high precision fields, temperature variation has more impact on the FOG outputs. In FOGs longer than 5.7 kilometers, the thermal phase noise replaces the light source’s relative intensity noise as the dominant noise. “The method of high-order frequency modulation is proposed in our work. WebPhase noise characterization of a 10-W Yb fiber amplifier is presented, and we demonstrate phase locking of two fiber amplifiers with near-perfect fringe contrast at power levels of …
