Abstract: | The theoretical and experimental validation was made to Lorenz function model of refractive index distribution in graded index polymer optical fiber (GI POF) by experimental data. It was found that simulating error is great when molecule bulk ratio is larger than one. According to calculating results, exponent parameter of the molecule bulk ratio in the model was corrected to 1.1, so the simulating error was remarkably reduced from ≤65% to <20%. It showed that influence of the molecule bulk ratio on refractive index distribution in GI POF is great. |
