- •
We fabricated a refractive index sensor based on in-fiber Michelson interferometer.
- •
The sensor has the advantages of short size (less than 2 mm) and easy fabrication.
- •
We use the method of intensity-modulated to solve cross sensitivity.
- •
The sensor has the sensitivity of −208.24 dB/RIU at the refractive index of 1.440.
- •
The sensor could apply in the fields of chemical and biomedical sensing.
