Influence of channel frequency spacing in multisource crosstalk in a Benes optical switch

摘要

Imperfect isolation of switching elements inside optical space switches gives rise to leakage signals that result in multisource crosstalk. The effects of this crosstalk are examined as a function of channel frequency spacing. A rigorous analysis of this phenomenon, based on Gauss quadrature rules method, is obtained considering a Benes architecture.
