Abstract
Refracted near-field method is a very mature and reliable method for the measure of fiber refractive index profiles. In this paper, we use refracted near-field technique and set up the experimental device to measure special optical fiber refractive index profiles. We build a simulation model which refers to air-core photonic crystal fiber based on refracted near-field method, determine the structure parameters and the relationship between refractive index profiles and light intensity distribution, calculate fiber refractive index profiles deviation caused by the special fiber structure, and give the correction method. The experimental result is modified by the above and obtains a good treatment effect.
