A new type of spiral photonic crystal fiber based on Archimedes spiral is proposed, and silica is chosen as the background material. The cladding is composed of 24 spiral arms, each spiral arm contains 11 small air holes, and there is a big air hole in the center of the fiber core. The annular area between the cladding and the air-core can transmit the orbital angular momentum mode. It can support stable transmission of 22 kinds of orbital angular momentum modes over the wavelength range of 1300~1800nm. The effective refractive index difference can be up to 2.89×10-3, the lowest dispersion can reach 66.4ps/(nm·km), and the nonlinear coefficient is minimally up to 2.17W-1·km-1 at 1550nm wavelength. The dispersion variation is less than 15.15ps/(nm·km) in the wavelength range of 1500~1600nm. The spiral photonic crystal fiber is not only simple in structure, but also has low nonlinearity and flat dispersion performance, which provides an idea for the design of spiral photonic crystal fiber.
