Analysis of intermodal coupling in a two-mode fiber with periodic microbends.
Simple expressions for the coupling between the LP(01) and LP(11) modes of a two-mode optical fiber with a periodic microbending structure are developed. Implementation of the microbend structure using a flexural acoustic wave is described. The dependences of the acoustic frequency and power requirements on the pertinent fiber parameters are presented.
