The mode transition and the dispersion turning point have been
explored for optimization of thin-film coated long period fiber gratings
during the last years. In this work and additional parameter, the cladding
diameter, is combined with the other two phenomena for improving the
sensitivity to the surrounding medium refractive index. The numerical data
obtained were calculated with a method based on the exact calculation of
core and cladding modes and the utilization of coupled mode theory. A
sensitivity 143 × 103 nm/RIU is obtained, the highest reported so far with
long period fiber gratings. [--]
