Abstract

Second-harmonic generation and others quadratic effects have attracted a great interest in the past few years. The renewal of these experimental and theoretical studies is essentially focused on cascaded χ⁽²⁾ effects. Our aim here is to concentrate on corrugated Zinc Sulfide thin film and take the advantage of the strong confinement of the resonantly excited guided waves. Surprisingly, dielectric thin films have not been intensively studied for their nonlinear optical properties as was be done for polymer thin films.
