We propose a design method for single-polarization photonic crystal fibers with improved beam quality by introducing the resonant coupling between the central core and the elliptical cores arranged on either side of the central core.

In this work, we report both theoretical and experimental efforts aimed at understanding the efficiency of using the method of fs modifications for the fabrication of highly non-linear photonic structures in bulk chalcogenide glasses. The research embraces: 1. numerical modelling of the process of glass sample illumination by a fs pulse, energy deposition and subsequent glass cooling; 2. melting of As-S-Se based chalcogenide glasses and measurement of their optical and thermal properties; 3. experiments on glass sample modification by fs pulses; 4. characterisation of the modified regions.

Spatial solitons observed in nematic liquid crystals, called as nematicons, possess unique properties that can be applied in all-optical switching and routing elements. Theoretical predictions and experimental results show the facility to steer direction of nematicons propagation both in 1+1 dimensional planar waveguides as well as in 2+1 dimensional structures. In this work we present the properties of nematicons in different configurations including twisted and chiral nematic liquid crystalline films. Due to the optical reorientational nonlinearity the spatial solitary waves were created for a light power of few tenths of milliwats at the distances of few millimeters.
