AI Article Synopsis

  • The research introduces the initial computation of Goos-Hänchen shifts related to nonlinear fields, focusing on second harmonic generation at metallic surfaces.
  • It highlights that significant harmonic generation and Goos-Hänchen shifts occur due to field discontinuities at these surfaces.
  • The findings can be applied to understand other types of shifts, including angular shifts and Fedorov-Imbert shifts.

Article Abstract

We present the first calculation of the Goos-Hänchen shifts in the context of the nonlinear generation of fields. We specifically concentrate on shifts of second harmonic generated at metallic surfaces. At metallic surfaces the second harmonic primarily arises from discontinuities of the field at surfaces which not only result in large harmonic generation but also in significant Goos-Hänchen shifts of the generated second harmonic. Our results can be extended to other shifts like angular shifts and Fedorov-Imbert shifts.

A new sensing scheme, capable of measuring various quantities using the Goos-Häanchen shift in the polarization phase domain, is proposed. The phase retardation between s and p polarizations on total reflection is enhanced by using multiple reflections in a plane-parallel transparent plate. This phase shift can be sensitively and stably detected using an in-line heterodyne method.
