Paper Abstract

We describe some of the theoretical explanations of efficient second-harmonic generation in Ge-doped glass optical fibers known in the literature, and we discuss two models that are based on the reorientation of GeE' centers by means of selective electronic transitions. The first model, which uses selective absorption of photons, stimulated experiments on fiber preparation under UV-excitation. The experimental results, in turn, stimulated modification of the model and the formulation of a selective emission model.
