Importance optical properties; effective refractive index, effective area, confinement loss and nonlinear coefficient have been studied. Each characteristic has been investigated in different air filling fraction of solid core Photonic Crystal Fiber. Finite Element Method had been used by using COMSOL MULTIPHYSICS 4.4 software, each iteration has been done within range of wavelengths 0.4 ttm to 2 ~tm with step 0.5 ~tm. The numerically simulated results showed that for the same filling air fraction and number of air holes rings around the solid core the effective refractive index and nonlinear coefficient decrease by the increasing of wavelength, while each of effective area and confinement loss increase by the increasing of wavelength. For each structure; effective refractive index, effective area and confinement loss decrease by increasing of air filling fraction and number of air holes rings around the solid core, while nonlinear coefficient increase, this could be useful for sensors applications that photonic crystal fiber could be designed according to application requirements.展开更多
