A. Vanhaudenardepeoch et R. Frey, DIFFERENT PHYSICAL SOURCES OF THE REFRACT IVE-INDEX VARIATION DURING PHOTODARKENING OF SEMICONDUCTOR-DOPED GLASSES, Annales de physique, 20(5-6), 1995, pp. 653-654
The refractive index variations occuring in semiconductor doped glasse
s are due to various sources of photo-induced static electric field. T
hese contributions are calculated and compared in order to evaluate un
der which experimental conditions, it is possible to obtain permanent
memories in such materials.
