‘Front induced transitions: light interaction with refractive index fronts in dispersive waveguides’

Abstract: Spatio-temporal modulation of light experiences a growing attention in recent years. Moving refractive index fronts in waveguides with dispersion is a special type of such modulation. The interaction of light with a front can be described in terms of an indirect transition where the frequency and wavenumber of a guided mode both are changed. Alexander will present theoretical and experimental examples of signal transmission, reflection and trapping by the front and highlight special situations such as light stopping, time reversal and optical push broom effect.
