T.R. Woliński, S. Ertman,  and K.A. Rutkowska     Warsaw University of Technology, Warsaw, Poland


The chapter discusses the latest developments in the field of photonic liquid crystal fibers (PLCFs) in view of their uses for electromagnetic field sensing. An overview of liquid crystals infiltrated microstructured optical fibers is presented and select issues related to electric field sensing with PLCFs are discussed. Apart from thermally, electrically, and magnetically induced effects, optically induced changes in the refractive indices of LC due to optical nonlinearity are demonstrated, including nonlinear discrete light propagation, spatial light ...
