An effective method to fabricate two-helix long-period fiber gratings (TH-LFGs) is presented.Based on the coupling mode theory,the conversion of optical vortices (OVs) in TH-LFGs are analyzed in detail.The conversions of OVs with different topological charges:0 → ±2 and 1 → 3 are simulated as three examples and the conversion efficiency higher than 98％ can be realized.
