Paper Abstract

We designed the large mode area photonic crystal fiber structure. We calculated the effective index, and dispersion of fundamental mode using finite difference time domain method. Numerical results show that fiber structure strips higher order modes from the photonic crystal fiber and retains only fundamental mode with 10cm bend. We have shown the results of two types of photonic crystal fibers. The fiber shows negative dispersion from 1.860 μm to 1.996 μm wavelength. We fabricated the photonic crystal fiber structure and analyzed the fabrication difficulties of the fiber design.
