Abstract :
We introduce a novel sensitive technique to characterize dynamic crosstalk in three-dimensional MEMS photonic crossconnects (PXCs). This nonintrusive technique enables end users to evaluate PXC dynamic performances without special access to the internal photonic-switching fabric. Our results confirm that while dynamic crosstalk can be significantly higher than static crosstalk, it has little system performance impact under normal operating conditions. We discuss methods to mitigate the effects of dynamic crosstalk.
