We theoretically investigate the blue light enhancement by the dual wavelength tunable Ti:sapphire laser in PCF. The blue light becomes broadened and extended to the short wavelength due to the cross phase modulation.

We present a theoretical analisys based on scattering in nematics and on two-level system for the dye action. A simple description of light diffusion is shown to be inadequate to describe processes at the basis of this lasing; different physical phenomena have to be considered.

We demonstrate symmetry breaking in a multistable system composed of three coupled nonlinear cavities. Using positive pulses it is possible to switch between the asymmetric states, thus resulting in tristable flip-flop behaviour. Coupled-mode theory gives analytical results and precise insight into the intricate dynamical behaviour.

Functional materials such as bulk crystalline semiconductor structures inside MOF waveguides could lead to fibre devices with radically new electronic and photonic degrees of freedom. We report the growth of such materials inside MOF templates via a novel microfluidic high pressure chemical vapour deposition technique.

The propagation and interaction of two-colour nematicons is considered in the local limit. Approximate equations governing the evolution of the pulses are derived based on a variational method and excellent agreement is found between the approximate equations and full numerical solutions of the nematicon equations.

We report our recent investigations of all-optical bistable switching/memory action toward all-optical logic, and novel adiabatic tuning phenomena (wavelength conversion, opto-mechanical energy conversion, and photon dynamic memory).
