Paper Abstract
Similarly to liquid crystal displays technology in photonic liquid crystal fibers (PLCFs) a molecular orientation control
is a crucial issue that influences proper operation of PLCF-based devices. The paper presents two distinct
configurations: planar and radial escaped orientation of the LC molecules inside capillaries as well as methods of their
application to photonic liquid crystal fibers. Possibilities of LC orientation control influence both: attenuation and
transmitting spectra of the PLCF
The orienting method is based on creation of an additional orienting layer on the inner surface of the capillary or air
hole of the photonic liquid crystal fiber. Aligning materials used in the experiment are commercially available
polyimides SE1211 and SE130 which induce liquid crystal homeotropic and planar anchoring conditions. The orienting
layer increase an order parameter of the liquid crystal improving propagation properties and stability of photonic liquid
crystal fiber-based devices.
