This study aimed to combine the use of a Mach-Zehnder type interferometer and the hydrogel volume phase transition theory to quantitatively model the refractive index dependence upon Ni2+ concentration. A highly sensitive refractive index sensor was achieved via fusion splicing, sandwiching a 3 cm p...
