In this paper, nematic liquid crystalline materials and its mesogenic and physicochemical properties (mainly birefringence, dielectric anisotropy, and viscosity) will be discussed. The influence of number and position of fluorosubstitution on the ability of nematic phase formation in broad temperature range and on the value and sign of dielectric anisotropy will also be demonstrated.

We show that the efficient non-phase-matched anti-Stokes Raman generation observed in gas-filled hollow-core PCF can be explained by "phase locking" of the interacting fields leading to the establishment of a phase difference independent of the optical path.

We show that the ratio of fiber loss to fiber nonlinearity is an important parameter for the design of pump resonators for fiber OPAs. Silica-based HNLF have advantages over other nonlinear fibers for making such resonators, and can exhibit power enhancement ratios of over 100.

An optical coupler constituted by a long-period grating (LPG) written into the single-mode core of a double- cladding photonic crystal fiber (DCPCF) is designed. The LPG allows an optimal power transfer from the inner cladding modes toward the fundamental mode guided in the core. The optical coupler feasibility is numerically demonstrated and its refinement is obtained via a large number of simulations. The calculations highlight that the 25% of the total input power is transferred from the inner cladding modes toward the fundamental mode guided into the core.

A new approach is proposed for computer simulation of radiation losses in photonic crystal fibers with multilayer Bragg reflecting cladding based on exact finite-difference method for Maxwell equations in cylindrical coordinates. Effectiveness of the approach is illustrated by leaky modes calculations in air and water filled hollow core fibers.
