Abstract: The combination of periodicity and nonlinearity is a powerfull means for controlling the properties of light. In this talk I propose to look at a variety of nonlinear aperiodic media including Bragg gratings photonic, crystal fibres, and quasi-phase-matched materials and show how a wide variety of nonlinear interactions ranging from second harmonic generation to super continuum generation benefit from the additional periodicity.
