Abstract

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. View Full-Text
