Abstract

What we believe to be a conceptually novel scheme for third-harmonic generation in engineered quasi-phase-matched ${\chi }^{\left(2\right)}$ optical structures is proposed in which the fundamental-frequency field is directly converted into the third-harmonic field without the intermediate generation of the second-harmonic field. This counterintuitive scheme, which exploits the concept of adiabatic passage and the existence of a nonlinear dark state, bears a close connection to the “stimulated Raman adiabatic passage” technique of population transfer in atomic physics.
