Refractometry is an important method for many applications in metrology, environmental monitoring, chemical and bio-medical sensing.
Several types of optical fiber refractometers have been developed including those based on fiber Bragg gratings (FBGs), long period gratings (LPGs), photonics crystal fibers (PCFs), and inline interferometers [1, 2]. Yet, all these approaches require complex fabrication procedures for fabricating a sensing structure.
