Abstract: | We investigate linear and nonlinear light propagation in the photonic crystal fibers infiltrated with nematic liquid crystals.
Such a photonic structure, with periodic modulation of refractive index, which could be additionally controlled by the temperature
and by the optical power, allows for the study of discrete optical phenomena. Our theoretical investigations, carried out
with the near infrared wavelength of 830 nm, for both focusing and defocusing Kerr-type nonlinearity, show the possibility
of the transverse light localization, which can result in the discrete soliton generation. In addition, we present the preliminary
experimental results on the linear light propagation in the photonic crystal fiber with the glycerin-water solution and 6CHBT
nematics, as the guest materials. |
