Orbital angular momentum (OAM) modes have attracted extensive attention for their wide range of applications in optical communications. OAM is considered to be promising way to increase the transmission capacity. As many as possible supported number of OAM modes in optical fiber could provide capacity increase critically. The structure design of the OAM supporting photonic crystal fiber (PCF) has recently attracted attention in optical communication research field. We proposed a new method to increase the orbital angular momentum modes up to 101 by increasing the number of air-holes at each layer from 35 to 55 in PCF, and find out that more air-holes can support more OAM modes. Additionally, higher refractive index difference, better mode quality and reduced dispersion could be achieved.
