Abstract

The cathodoluminescence technique has been used to analyze germanosilicate optical fiber preforms fabricated by the MCVD process. The distributions E' and drawing-induced defects have been measured and the effects of some co-dopants and fabrication conditions on the distributions have been investigated. The results have been explained in terms of a simple reaction scheme involving the electron donor and acceptor properties of co-dopants.
