BER Evaluation of a Passive SOI WDM Router
Résumé
The performance of a ring-resonator based passive wavelength router, suitable for optical networking at chip level, is evaluated through BER measurements in single channel 10 Gbit/s and 3-channel 10 Gbit/s WDM configurations. As the routing path involves a different number of routing elements, depending on the wavelength used for the propagating signal, the performance of three output ports with respect to a specified input one are experimentally evaluated and discussed. Measurements show that low rejection on the filter elements due to fabrication issues mostly affect the channel on the through path with respect to the dropped ones.
