摘　　要：光纤与有机聚合物脊形波导的耦合是有机聚合物波导器件封装中关键的一步,它直接影响器件的插入损耗。本文利用广角有限差分束传播法和有效折射率法对光纤与有机聚合物脊形波导的耦合损耗进行分析,得出了如下结论:1)耦合损耗随着错位、间隙、夹角的增大而增大;2)因错位而引起的耦合损耗在所有耦合损耗中占有主要位置。The coupling between optical fiber and polymeric rib waveguide is a key step of device packaging and directly affects the inserting loss of the device. The coupling loss between optical fiber and polymeric rib waveguide was analyzed with Wide-Angle Finite-Difference Beam Propagation Method （FD-BPM） and Effective Index Method （EIM）. The conclusions are as follows： l） the coupling loss increases with the increasing of dislocation, gap and angle between optical fiber and Polymeric Rib Waveguide; 2） the coupling loss induced by the dislocation plays a main role in all the coupling loss.
