Ultrahigh-temperature regenerated gratings in boron-codoped germanosilicate optical fiber using 193 nm

Opt Lett. 2008 Aug 15;33(16):1917-9. doi: 10.1364/ol.33.001917.

Abstract

Regenerated gratings seeded by type I gratings in boron-codoped germanosilicate optical fiber written with 193 nm are shown to withstand temperatures beyond 1000 degrees C.
