摘要：
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.
