We show that, in a χ(2) material, a backward injected signal beam undergoes an automatic π phase shift in a phase-matched cascaded parametric interaction in the presence of a forward injected pump beam. This type of interaction, compared with the previously proposed copropagative cascaded parametric interaction configurations, is shown to have more flexibility for signal processing.

Abstract
We show that, in a χ(2) material, a backward injected signal beam undergoes an automatic π phase shift in a phase-matched cascaded parametric interaction in the presence of a forward injected pump beam. This type of interaction, compared with the previously proposed copropagative cascaded parametric interaction configurations, is shown to have more flexibility for signal processing.File in questo prodotto:
