title: Enhanced type IIA gratings for high-temperature operation.
abstract: The inscription of type IIA fiber Bragg gratings in standard boron-codoped germanosilicate fiber has been demonstrated to show marked differences from that reported in the literature. These gratings were subjected to high temperatures, and their decay behavior was evaluated. Gratings resistant to heat up to 800 degrees C for a moderate length of time are demonstrated.
