Abstract

In this paper, a novel dual-guided microstructured fiber supporting orbital angular momentum (OAM) mode and linear polarization (LP) mode transmission is proposed to solve the high-volume data transmission. A variety of parameters of the fiber are considered comprehensively under different conditions by using the full-vector finite element method. The results show that the fiber can support 30 OAM modes and 2 LP modes over the whole C wavelength band by making full use of the air-holes to isolate electromagnetic field. The crosstalk between two channels is lower than that previously reported, and the total dispersion is nearly zero and flat. For instance, the isolation parameter of the EH71 mode reaches up to 86.02 dB and the dispersion coefficient varies from −  0.26 to 1.62 ps/(km nm). The large index difference between core and cladding is beneficial to low crosstalk. In addition, this fiber is easier to fabricate, because the preform needs only stacking technique to adjust the structure geometry size. This fiber can be used in short-distance and large-capacity transmission system.
