High-sensitivity and large-dynamic-range fiber refractometer based on composite-cavity Fabry-Perot structure


Most sensors have the tradeoff dilemma of high sensitivity and large dynamic range. We demonstrate here an all-fiber refractive index sensor based on a composite intrinsic Fabry-Perot interferometer (FPI), which possesses the co-existence advantages of high sensitivity and large dynamic range. Experimental trends are in good agreement with the theoretical predictions. The co-existence of high sensitivity and large dynamic range in a composite FPI is of great significance to practical refractive index measurement.
