We investigate through a formalism similar to a coupled mode theory in time, the behavior of a system composed by a direct coupled cavity with inside it a quantum dot in cascade configuration. We derive the conditions for which switching can be achieved. Two quantum optical effects are considered: vacuum Rabi splitting and the Autler-Town doublet.

We have investigated the nonlinear light propagation in photonic crystal fibers filled with nematic liquid crystals. Light with a frequency within the photonic bandgap is propagating in the central glass core being the structure defect. Outside the bandgap analyzed fiber corresponds to the matrix of liquid crystalline waveguides. The changes of refractive index due to the temperature or/and nonlinear effects can lead to the bandgap shifting. As a consequence the incident beam with a frequency initially within the bandgap is then turned outside the bandgap resulting in the changing of the propagation for the discrete diffraction effect.

Liquid crystals, functionalized with ferroelectric, inorganic nanoparticles, show improved photorefractive response. Three-fold increase in dielectric anisotropy and optical anisotropy was measured, as well as significant improvement in two-beam coupling gain.

We describe a technique for achieving polarization-independent nonlinear interactions in a short nonlinear fiber, through the residual birefringence of the fiber. We apply this method to all-optical demultiplexing of high data rate signals.

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.
