Light propagation in tuneable nonlinear periodic photonic structures
The action of light in periodic structures can be quite different to that in a homogenous medium. For example, while a nonlinear beam will spread out in a medium with a negative nonlinearity, in a periodic structure the beam is focused and a localised state is formed. In this thesis I will show my work on light propagation in tuneable nonlinear periodic photonic structures. Nature provides us with dazzling displays of periodic photonic structures in the form of butterfly wings, peacock...[Show more]
