Abstract

We numerically designed and engineered an isopropanol-silica based photonic crystal fiber for the coherent supercontinuum generation at 1300 nm and 1600 nm for optical coherence tomography. We have adopted the finite element based technique to calculate the effective mode index with its effective mode area of the fundamental mode at different wavelengths. With effective dispersion tailoring techniques, we have optimized the geometrical dimensions of the fiber and obtained the dispersion value as -27.35 ps/nm/km and +25.4 ps/nm/km at 1300 nm and 1600 nm respectively. We have obtained the nonlinear coefficient values at 1300 nm as 21.80 W^-1km^-1 and at 1600 nm as 13.79 W^-1km^-1. The proposed design can be proven an efficient and true fiber model for the generation of highly coherent supercontinuum broadband source.
