Abstract

A study of signal polarization state evolution in an amplified recirculating delay line (RDL) signal processor is presented. It shows that the change in the RDL signal polarization states behaves periodically, which can be described by a sinusoidal function. This change significantly alters the RDL signal processor frequency response shape when a polarization dependent component is connected at the signal processor output. Results demonstrate the validity of the equation that is used to predict the frequency response shape of the amplified RDL filter for different signal polarization state evolutions.
