A simple structure of all-solid microstructured fiber, which is composed of 8 linear arrays of high refractive index dielectric rods radially symmetry arranged around a low refractive index substrate, is proposed and numerically investigated. The calculated results show that the space between the adjacent band gaps is very small, minimum loss of 0.35 dB/km can be achieved. With increasing the distance between high refractive index rods and the refractive index difference between the high refractive index rod and the core, the band gap will move to the long wavelength. With decreasing the bending radius, the short wavelength edge of PBG is significantly affected and shifts to the long wavelength, while long wavelength edge of PBG suffers relatively little impact. By adjusting the layer number of high refractive index dielectric rods, we can effectively change the effective mode area, resulting in large mode area fiber.
