Description
Mode-locked fiber comb equipped with multi-mode-interference fiber sensor functions as high-precision refractive-index (RI) sensor benefitting from precise radio-frequency measurement. However, its dynamic range and repeatability are hampered by inherent characteristics in nonlinear-polarization-rotation mode-locking oscillation. In this article, we introduce saturable-absorber-mirror mode-locking for RI sensing with wide dynamic range and high repeatability. While the RI dynamic range was expanded to 41.4 dB due to high robustness to cavity disturbance, self-starting capability without the need for polarization control improves the RI sensing repeatability to 1.10×10-8 every mode-locking activation. Improved dynamic range and repeatability will be useful for enhanced performance of RI sensing.
