Abstract
A Sm+2/Sm+3 codoped aluminosilicate glass optical fiber was fabricated by use of modified chemical-vapor deposition in conjunction with an a erosol-delivery technique. A permanent index change of 7.6 x 10(-5) wa s induced in the fiber by irradiation of 1 W of multiline output from an Ar-ion laser. Bleaching of a broad absorption band of Sm+2 in the v isible range was also observed, and it is believed that photoionizatio n of Sm+2 --> Sm+3 + e plays an important role in the induced photoref ractivity.
