“…The main source of cross-talk in FLC is the imperfect alignment of LC molecules. In one of the previous work, Fracasso et al developed a free-space switch based on the FLC material [38]. Cross-talk in the developed 1 × 14 single-stage switch varies from −21 dB to −45 dB in between the addressed and non-addressed fibers with the switching time only in the order of sub-millisecond.…”

The present work explains simulation and experimental investigation of the most significant performance parameters of a ferroelectric liquid crystal (FLC) optical switch. The measurements were carried out with commercially available FLC mixture (θ = 22.5 • ), having a very fast response time within the range of 1-10 µs. The best achieved cross talk was~19 dB, which is an exact match with the theoretical result.
