Abstract:For suppressing nonlinear effect in ROF system,two modulation techniques based on multi-arm M-Z modulators are proposed.First,both the modulation methods and principles of the two techniques are described theoretically,and then,with the help of optical communication simulation software-Optisystem,simulation analysis about ROF systems based on these techniques are carried out,comparing with ROF system based on traditional M-Z modulators.The results show that: the two modulation techniques effectively reduced the nonlinearity of the ROF systems,and the range of modulation index system can accept was expanded.
Keywords:nonlinearity  multi-arm M-Z modulators  ROF  optisystem
