A large effective mode area photonic crystal fiber supporting 134 OAM modes

A novel photonic crystal fiber (PCF) based on silica is designed for stable transmission of orbital angular momentum (OAM) modes. Numerical analysis shows that the PCF can support more than 134 OAM modes in a broad wavelength range of 1200–2000 nm. In addition, it boasts a large effective mode area...

Summary:A novel photonic crystal fiber (PCF) based on silica is designed for stable transmission of orbital angular momentum (OAM) modes. Numerical analysis shows that the PCF can support more than 134 OAM modes in a broad wavelength range of 1200–2000 nm. In addition, it boasts a large effective mode area between 259.97–423.99 μm 2 , confinement loss of all the eigenmodes at 10 −9 –10 −10  dB/m, nonlinear coefficients within 0.47 W −1 /km with the minimum being 0.25 W −1 /km at 1550 nm. The excellent properties reveal that the PCF has large potential in ultra-high capacity OAM mode division multiplexing for fiber communication systems.
