A colour-centre model for second-order optical nonlinearities in germanosilicate optical fibres
Second-order nonlinearities can be induced in germanosilicate (GS) glass fibers in a variety of ways: by coherent superposition of pump and second-harmonic light (a third-order dc polarization Pdc is induced that breaks the inversion symmetry); by excitation poling with blue light and an external dc field, Epol ; and by strong Epols 's in the absence of light. There is as yet no satisfactory agreement over the nature of the underlying alignment process. From related detailed studies of color-center behavior in GS fiber, we have formulated a self-consistent model as developed in the following points.

Abstract

Second-order nonlinearities can be induced in germanosilicate (GS) glass fibers in a variety of ways: by coherent superposition of pump and second-harmonic light (a third-order dc polarization Pdc is induced that breaks the inversion symmetry); by excitation poling with blue light and an external dc field, Epol ; and by strong Epols 's in the absence of light. There is as yet no satisfactory agreement over the nature of the underlying alignment process. From related detailed studies of color-center behavior in GS fiber, we have formulated a self-consistent model as developed in the following points.
