Abstract
Photonic liquid crystal fibers (PLCFs) can be categorized in two principal
groups: index guiding PLCFs and photonic bandgap PLCFs. In this paper we
focus on index guiding PLCFs in which effective refractive index of the
micro structured cladding filled with liquid crystal is lower than
refractive index of the fiber core. In these fibers broadband propagation of
light is observed and also effective tuning of guiding properties is
possible. In this paper PLCFs with tunable attenuation, retardation and
polarization dependent losses are reported. We also enumerate some potential
applications of index-guiding PLCFs, together with discussion of few
technical issues important in the context of future development (i.e.,
effective electrical steering and connecting with standard fibers).
