We report a miniaturized fiber probe inline reflective interferometer (FPIRI) sensor, with a several μ-micro-notch cavity fabricated for highly sensitive refractive index measurement. Its sensitivity in liquid is ~100 nm/RIU (refractive index unit) near the wavelength of 1550 nm with a high extinction ratio. This probe sensor is very compact, stable, and cheap, offering great potentials for detecting inside sub-wavelength particles or biocells.
