High-Sensitivity, Large Dynamic Range Refractive Index Measurement Using an Optical Microfiber Coupler
Wavelength tracking methods are widely employed in fiber-optic interferometers, but they suffer from the problem of fringe order ambiguity, which limits the dynamic range within half of the free spectral range. Here, we propose a new sensing strategy utilizing the unique property of the dispersion t...
